Tail Drop: Burly Rear Shock Lowering Kit for Harley Sportster (2000–2003)

The Burly Rear Shock Lowering Kit is an extremely popular and budget-friendly component designed to lower the rear ride height of the Harley-Davidson Sportster (XL) models from 2000 through 2003.

This kit utilizes lowering blocks/brackets to achieve a custom stance while retaining your original factory-length shocks.

Key Features and Lowering Mechanism

Manufacturer Part # (Black): B28-260

Drop Amount: This specific lowering block kit is designed to drop the rear ride height by approximately 1 inch (1.00″).

Mechanism (Lowering Blocks): The kit consists of high-strength, powder-coated steel brackets/blocks. These are installed at the lower mounting point of the external rear shocks, effectively relocating the shock’s anchor point to reduce the bike’s resting height.

Cost-Effective: It is an inexpensive, quick-to-install alternative to purchasing a new set of shorter shocks.

Compatibility: Designed for use with OEM and most aftermarket stock-length shocks on the 2000-2003 Sportster models.

Fitment and Exclusions (2000–2003 Sportster)

This kit fits most standard-height Harley Sportster models (XL) in the 2000-2003 range, including:

XLH883 (Standard, Hugger, Custom)

XLH1200 (Standard, Custom, Sport)

Important Exclusions:

Hugger & Custom Models: Some listings warn that this kit may NOT fit factory-lowered models like the Hugger (XLH883HUG) or Custom (XL1200C/XL883C), as these bikes already have shorter shocks/travel, and lowering further can cause immediate clearance issues.

Shorty Shocks: Crucially, it is NOT to be used in conjunction with “shorty” or “low-profile” shocks (like Burly’s own 10.5″ Slammer shocks). The combined drop would eliminate virtually all travel and cause tire-to-fender or frame-to-belt contact.

Installation and Warnings

Installation: This is a simple bolt-on installation of the brackets/blocks.

Ground Clearance: Even a 1-inch drop reduces your lean angle. It is mandatory to check clearances:

Tire-to-fender contact (must be less than 9.0 inches from center-to-center shock mount measurement at the contact point).

Fender-to-belt/belt guard clearance.

Frame-to-exhaust clearance.

Jiffy Stand: Check the motorcycle’s parking lean angle after installation. Your stock kickstand may need to be shortened or replaced for stability.

If you are looking for a more dramatic drop (up to 2.5 inches), Burly’s Slammer Shocks (10.5″ eye-to-eye replacement shocks) are the alternative, though they are more expensive and offer a much stiffer ride.

Tail Drop: Burly Rear Shock Lowering Kit for Harley Touring (2009–2016)

The Burly Rear Shock Lowering Kit (Manufacturer Part No. B28-42008) is an extremely popular and cost-effective component designed to lower the rear end of Harley-Davidson Twin Cam Touring models from 2009 through 2016.

This kit is valued for its simple installation and is often the quickest way to achieve a custom, lowered stance while keeping the factory shock absorbers.

Key Features and Lowering Mechanism

Mechanism (Lowering Blocks): The kit utilizes a pair of high-strength lowering blocks/brackets made from powder-coated black steel. These blocks bolt onto the lower shock mount, effectively changing the geometry to lower the bike’s resting height.

Drop Amount: This specific Burly kit is designed to provide approximately a 1-inch (1.00″) drop in the rear ride height.

Cost-Effective: It is marketed as an inexpensive alternative to purchasing a full set of shorter, low-profile shocks (like the Burly Slammer Shocks).

Compatibility: Designed for use with OEM or aftermarket stock-length shocks.

Fitment and Exclusions (2009–2016 Touring)

This kit fits most standard-height Harley Touring models (FLH/FLT) in the 2009-2016 range:

Road King (FLHR)

Electra Glide Classic/Ultra Classic (FLHTC/U)

Road Glide Custom/Ultra (FLTRX/U)

Ultra Limited (FLHTK)

Important Exclusions:

“Low” Models: Does NOT fit models that were factory-lowered (e.g., Street Glide/FLHX, Road Glide Special/FLTRXS, or “Low” versions of other models).

Trikes: Not for use on Trike models.

Shorty Shocks: Crucially, it is not to be used in conjunction with “shorty” or “low-profile” shocks to avoid severe clearance issues and bottoming out.

Coil-Over Adjustable Shocks: Some sources indicate it is not for use with the specific coil-over adjustable shocks found on some later CVO or premium models.

Installation and Warnings

Installation: The lowering blocks are a simple bolt-on installation, often requiring less than an hour for an experienced mechanic.

Trade-offs (Ground Clearance): A 1-inch drop reduces your lean angle. It is essential to check tire-to-fender, fender-to-belt, and frame-to-exhaust clearance after installation.

Saddlebags: Some riders report that the altered shock angle may require spacing out the saddlebags slightly to prevent interference.

Handling: While the drop is moderate, lowering blocks inherently change the angle of the shock relative to the swingarm, which can slightly alter the shock’s damping efficiency and overall ride performance compared to shorter shocks that maintain the correct angle.

This Burly Rear Shock Lowering Kit is a straightforward and economical way to achieve a lowered look on your 2009–2016 Harley Touring bike.

Low-Rider Drop: Burly Rear Lowering Kit for Harley Dyna (2006–2017)

The Burly Rear Lowering Kit (Part B28-22007 for black finish) is a specific component designed to lower the rear ride height of the Harley-Davidson Dyna models equipped with dual external shocks, spanning 2006 through 2017.

This kit is an economical and effective way to achieve a custom stance and better ground reach without replacing your stock shock absorbers entirely.
Key Features and Lowering Mechanism

Drop Amount: This specific Burly kit is designed to provide a 1-inch (1.00″) drop in rear ride height.

Note: While the full Burly Slammer Kit replaces the shocks with a 10.5-inch unit for up to 2.5 inches of drop, this “lowering block” kit is a more moderate 1-inch change.

Mechanism (Lowering Blocks): The kit consists of high-strength lowering blocks/brackets that install between the stock rear shocks and the swingarm. By effectively relocating the lower shock mounting point, the blocks reduce the bike’s resting height.

Compatibility: Designed specifically for the OEM and most aftermarket stock-length shocks on the 2006–2017 Dyna platform.

Finish: Commonly available in Black Powder-Coated steel (B28-22007) for a clean look that matches the frame.

Fitment and Exclusions

The Burly Rear Lowering Block Kit fits most 2006–2017 Twin Cam Dyna models, including:

Street Bob (FXDB)

Super Glide (FXD, FXDC)

Low Rider (FXDL)

Fat Bob (FXDF)

Wide Glide (FXDWG)

Exclusion: The kit typically excludes the Switchback (FLD) models (2012–2016) due to their unique geometry and specific shock requirements.

Installation and Important Warnings

Installation: The lowering blocks are a relatively simple bolt-on installation requiring a bike lift and basic tools to swap the mounting hardware.

DO NOT Use with Shorty Shocks: Crucial Warning: Burly specifically states this kit is not to be used in conjunction with “shorty” or “low-profile” shocks. Doing so would reduce travel too severely, leading to tire-to-fender rub and bottoming out.

Ground Clearance: Even a 1-inch drop will reduce your lean angle. Always check fender-to-belt, tire clearance, and exhaust clearance after installation.

Jiffy Stand: Check the motorcycle’s parking lean angle after installation. Your stock kickstand may need to be shortened or replaced to ensure stability.

This Burly Rear Lowering Kit is a popular and cost-effective way to achieve a 1-inch drop on your 2006–2017 Dyna while retaining your factory shock performance and adjustability.

Tunable Drop: Burly Adjustable Rear Lowering Kit for Harley Softail (2000–2017)

The Burly Adjustable Rear Lowering Kit (Part B28-257 series) is a high-quality, adjustable solution designed to lower the ride height of Harley-Davidson Twin Cam Softail models spanning 2000 through 2017.

This kit is valued for its ability to fine-tune the lowered stance and for its clean, internal appearance since it modifies the hidden rear shocks.
Key Features and Adjustable Drop

Adjustable Drop Range: The kit allows the rear ride height to be adjusted from approximately 0 inches (stock height) down to 1.25 inches (1-1/4″) lower than stock.

Some generic listings advertise 2 inches, but Burly’s official product specifications often cite a recommended maximum drop of 1.25 inches for safe operation and handling.

Mechanism (Internal Modification): This kit replaces internal components (the shock stub shaft) within the hidden Softail shocks. It utilizes an adjustable screw-in shaft that allows the effective eye-to-eye length of the shock to be precisely set, thus adjusting the rear ride height.

On-Bike Adjustability: Crucially, the adjustable design allows for changes in ride height to be made without having to remove the shock mounting bolts or completely remove the shock assemblies from the bike.

Compatibility: Designed to work with the Original Equipment (OE) Softail shocks of the Twin Cam era (2000–2017).

Durable Design: The kit features a sealed design to protect the heim bearings and is typically made from zinc-plated or chrome-plated high-strength steel.

Fitment and Installation Notes

Model Coverage: Fits most FXST/FLST Softail models from 2000 through 2017 (e.g., Fat Boy, Heritage Classic, Night Train).

Installation Difficulty: While the kit is adjustable once installed, the initial installation requires removing the rear shocks, disassembling the rear shock internals to replace the stock stub shaft with the adjustable Burly component, and reinstalling. This job is usually rated as moderately difficult due to the location of the shocks under the transmission and the need for specialized tools (like a shock spanner wrench).

Important Trade-offs

Ground Clearance: Even a 1.25-inch drop will significantly reduce your motorcycle’s lean angle. Always check for clearance issues with exhaust and floorboards/footpegs.

Ride Quality and Preload: Lowering the ride height reduces the available suspension travel. Burly recommends re-adjusting the spring preload after installation to compensate for the reduction and achieve proper “sag,” which is essential for maintaining the best possible ride quality.

Kickstand Check: You must check your motorcycle for the proper parking lean angle after installation. Your stock jiffy stand may require modification or replacement.

This Burly Adjustable Rear Lowering Kit provides a precise and clean way to achieve a custom lowered stance on your Twin Cam Softail.

Ultra-Easy Drop: Burnout Cycles Softail Lowering Kit (2000–2017)

The Burnout Cycles Softail Lowering Kit is a highly popular and well-known rear suspension modification designed to drop the ride height of Harley-Davidson Twin Cam Softail models from 2000 through 2017.

This kit is renowned for its simplicity and is often cited as one of the easiest ways to achieve a custom, slammed look on a Softail without fully disassembling the hidden rear shocks.

Key Features and Lowering Mechanism

Maximum Drop: The kit typically allows the rear end to be lowered by up to 2.25 inches (with options for a 1.5-inch or 2-inch drop often included in the same package).

Mechanism (Bolt-On/Collar System): Unlike kits that require internal shock disassembly (like Progressive’s), Burnout Cycles designed a bolt-on extension shaft or collar system that mounts to the existing shock post. This effectively lengthens the shock’s mounting point, reducing the overall ride height.

Note: Older versions extended the shock post; newer kits sometimes use an external collar.

Ease of Installation: The primary selling point is that installation is designed to be completed without removing the shocks from the bike or taking the shocks apart (no spring compressor needed). This drastically reduces installation time and complexity.

Customizable: Kits often come with components allowing the user to select the final drop amount (e.g., 1.5 inches for better ride quality, or 2 inches for a full slam).

Fitment and Compatibility

Wide Range: Designed to fit most Harley-Davidson Softail Twin Cam models from 2000 through 2017, including:

Fat Boy (FLSTF/FLSTFB)

Heritage Classic (FLSTC)

Softail Standard (FXST)

Night Train (FXSTB)

Deuce (FXSTD)

Rocker/Rocker C (FXCW/FXCWC)

Softail Slim (FLS)

Breakout (FXSB)

Target Shock: Intended to be used with the Original Equipment (OE) Softail shocks.

Important Trade-offs

Ground Clearance: Lowering the rear by 2 inches significantly reduces the motorcycle’s lean angle. Aggressive riders must exercise caution to avoid scraping exhaust, floorboards, or other hard parts.

Ride Quality: The adjustable nature helps, but reducing the available shock travel by up to 2 inches will make the ride noticeably firmer and harsher over large bumps compared to the stock ride height.

Adjustments: It is crucial after installation to check tire-to-fender clearance and adjust the drop height as necessary, as a full 2-inch drop may cause rubbing on certain tire/fender combinations.

The Burnout Cycles Softail Lowering Kit is an excellent choice for the Softail owner who wants a dramatic, custom drop with the absolute least amount of installation effort.

Slammed Stance: Progressive Rear Lowering Kit for Harley Softail (1989–1999)

The Progressive Suspension Rear Lowering Kit is a highly popular and economical way to lower the rear ride height of the Harley-Davidson Evolution-era Softail models spanning 1989 through 1999.

This kit (Manufacturer Part No. 30-5046C) is designed to be fully adjustable and provides a low, custom stance by modifying the stock or aftermarket Progressive shocks hidden beneath the bike.

Key Features and Lowering Mechanism

Adjustable Drop: This kit allows the rider to adjust the rear ride height anywhere from stock height down to 2 inches lower than stock. This adjustability is key for fine-tuning the look and balancing the ride quality.

Mechanism: Unlike external lowering blocks used on other platforms, this Progressive kit works internally. It consists of adjustable threaded bolts/caps that replace the stock adjuster caps on the hidden Softail shocks. By adjusting the length of these components, the overall eye-to-eye length of the shock is shortened, thus lowering the bike.

Shock Compatibility: The kit is designed to work with both the Original Equipment (OE) Softail shocks AND Progressive Suspension’s own Softail shocks (like the 422 Series).

Construction: Typically made from high-strength material (often chromed steel) for durability and corrosion resistance.

Fitment and Compatibility

The Progressive 30-5046C lowering kit is a direct fit for most Harley Softail models from 1989 through 1999, which include the Evolution engine and the pre-2000 style hidden shocks:

Softail Standard (FXST)

Softail Custom (FXSTC)

Fat Boy (FLSTF)

Heritage Classic (FLSTC)

Heritage Springer (FLSTS)

And other related FXST/FLST models from this era.

Installation and Trade-offs

Installation: Installation requires access to the hidden rear shocks (often under the transmission) and specialized spanner wrenches to remove the stock caps and thread in the new adjustable lowering bolts.

Ground Clearance: Lowering the rear by 2 inches significantly reduces the motorcycle’s lean angle. Riders should be cautious of scraping footpegs, floorboards, or exhaust components during aggressive cornering.

Ride Quality: Lowering the bike drastically reduces the available suspension travel. While the Softail’s hidden shock design makes the ride inherently softer than a twin-shock bike, a 2-inch drop will make the ride significantly firmer and harsher over large bumps.

The Progressive Softail Lowering Kit is considered a great option for the 1989–1999 Softail because it is a clean, internal modification that provides a custom look with adjustable height.

Lowboy Stance: Burly Fork Lowering Kit for Harley (1987–2015)

The Burly Fork Lowering Kit (often called the Lowboy kit) is a versatile front suspension modification designed to drop the front end of a massive range of Harley-Davidson models from 1987 through 2015.

Because this era covers many different models and fork sizes, Burly provides different part numbers depending on the fork diameter: 39mm, 41mm, or 49mm.
Key Features of the Burly Fork Lowering Kit

Lowering Options: The kit includes components that allow the installer to choose between a 1-inch or 2-inch drop in front ride height.

Progressive Rate Springs: A key component is the progressively wound fork springs. They are softer initially for comfort but stiffen rapidly to resist bottoming out on the reduced travel.

Improved Handling: The firmer springs help reduce front-end dive during hard braking, a common issue on stock Harley suspension.

“Drop-In” Design: The kit is designed to install with only minor fork disassembly (no need to completely remove the fork legs from the triple trees for all models), simplifying the installation process.
Important Trade-offs and Warnings

Ground Clearance: Lowering the front end reduces ground clearance and, more importantly, the available lean angle. Aggressive riders will scrape sooner in corners.

Touring Warning: Burly specifically advises Do Not lower FLH/FLT (Touring) models 2 inches. The maximum safe drop for these heavier models is typically 1 inch.

Required Maintenance: Installation typically requires draining the fork oil and involves replacing the internal rebound springs on the damper rod to achieve the desired drop height. It is a good time to check/replace your fork seals.

Jiffy Stand: You must check your motorcycle’s parking lean angle after lowering. A significant drop (especially 2 inches) may require a shorter kickstand for safe parking stability.

Burly Fork Lowering Kit For Harley

These Fork Lowering Kits allow for the bike to be easily lowered to the ground but allows for enough clearance where you won’t be tanking any damage. Progressively wound springs deliver a compliant ride, yet resist bottoming. Kit includes components to lower bike up to 2 inches.
Features:

Requires disassembly of forks
Includes components to lower bike 2″

Lowboy Stance: Burly Fork Lowering Kit for Harley Big Twin (1980–2013)

The Burly Fork Lowering Kit (often called the Lowboy kit) is a highly versatile front suspension component designed to drop the front end of a vast array of Harley-Davidson Big Twin models from 1980 through 2013.

This kit primarily targets the numerous models that utilize the 41mm Showa fork tube diameter, which was the standard Big Twin fork for decades.
Key Features and Drop Amount

Part Number: The primary part number for the 41mm forks in this range is typically B28-100.

Lowering Options: The kit includes components that allow the installer to choose between a 1-inch or 2-inch drop in front ride height.

Progressive Rate Springs: A central feature is the inclusion of progressively wound fork springs. This design is essential for lowered setups: it provides a comfortable, soft initial feel but quickly stiffens to resist harsh bottoming with the reduced travel.

Improved Handling: The stiffer, progressive springs also help reduce front-end “dive” during hard braking.

Broad Fitment (41mm Forks)

The Burly B28-100 kit covers the 41mm fork models across the following Big Twin platforms in this era:

Touring (FLH/FLT): Fits most models from 1980 through 2013 (e.g., Road King, Electra Glide, Street Glide).

Note: Burly specifically warns: Do Not lower FLH models 2″. (The maximum safe drop for Touring models is 1″).

Softail (FXST/FLST): Fits most models from 1984 through 2013 (e.g., Fat Boy, Heritage Classic, Softail Standard).

Dyna: Fits Dyna Wide Glide (FXDWG) models from 1992 through 2005.

Installation Notes (Drop-In Design)

While called a “Drop-In” system, installation for 41mm forks is more involved than just replacing the top spring.

Requires Partial Disassembly: The process requires removing the fork oil, the fork cap, and the damper rod bolt at the bottom of the fork leg to replace the rebound spring with the supplied longer unit (or stacking both springs for the 2″ drop).

Adjusting Drop:

1-inch Reduction: Uses the longer rebound spring supplied in the kit.

2-inch Reduction: Uses both the supplied longer rebound spring and the stock rebound spring stacked together (Do not use this option on Touring models).

No Complete Seal Replacement: The easy part is that you usually do not need to remove the fork seals or completely disassemble the fork leg from the triple trees.

Important Trade-offs

Ground Clearance: Lowering the front end reduces ground clearance and, combined with a lowered rear, will reduce the bike’s available lean angle.

Jiffy Stand: If you lower both the front and rear, you may need to bend or replace your jiffy stand to ensure the bike is stable when parked.

Burly Fork Lowering Kit For Harley Big Twin

These Fork Lowering Kits allow for the bike to be easily lowered to the ground but allows for enough clearance where you won’t be tanking any damage. Progressively wound springs deliver a compliant ride, yet resist bottoming. Kit includes components to lower bike up to 2 inches.
Features:

Requires disassembly of forks
Lowers your forks up to 2″ (one inch on FLT/FLHT models)
