Burly Slammer Kit For Harley Sportster 2004-2015
Full Stance Drop: Burly Slammer Kit for Harley Sportster (2004–2015)
The Burly Slammer Kit is the most popular all-in-one suspension solution for riders looking to give their Harley-Davidson Sportster (XL) models (2004–2015) a dramatic, slammed, custom stance. This complete package provides both the specialized fork springs and short rear shocks necessary to lower the bike significantly, front and rear, for an aggressive profile and improved ground reach.
Installation and Design Features
The kit is known for its simplicity, making a full suspension drop manageable for the home mechanic:
“Drop-In” Front Springs: The fork springs are a special design that allows for installation without requiring full fork leg disassembly (like removing the lower legs). This saves significant time and specialty tools.
Progressive Rate Springs: Both the front springs and the rear shocks feature progressive wound springs. They are tuned to be soft initially for better comfort but quickly ramp up stiffness to resist harsh bottoming when operating with reduced travel.
Rear Shock Adjustability: The 10.5″ rear shocks typically include a cam-style preload adjuster for easy firmness adjustments to compensate for a passenger or luggage.
Fitment and Compatibility
Wide Model Coverage: Fits most Harley Sportster models (XL) from 2004 through 2015 (e.g., Iron 883, Forty-Eight, 1200 Custom, Roadster).
Exclusions: Generally does not fit the new Revolution Max-powered models (Sportster S/Nightster) or specialized earlier models like the Sportster Sport (XL1200S).
Important Trade-offs
Riders should be fully aware of the trade-offs when installing the Burly Slammer Kit:
Ground Clearance: The primary trade-off is significantly reduced lean angle and ground clearance. Footpegs, floorboards, and exhaust components will scrape sooner in corners.
Ride Quality: Due to the drastic reduction in suspension travel (up to 2.5 inches in the rear), the ride will be firmer and harsher over large bumps and rough pavement compared to stock or longer aftermarket shocks.
Jiffy Stand: A shorter kickstand is highly recommended or may be required to ensure the bike leans securely when parked due to the reduced ride height.
The Burly Slammer Kit Sportster 2004-2015 is the top choice for riders prioritizing a low, aggressive stance and improved ground reach.
