Progressive 422 Shocks For Harley Softail 2000-2017
That is an excellent choice for upgrading your Harley-Davidson Softail (2000-2017)! The Progressive Suspension 422 Series Shocks are one of the most popular aftermarket solutions for replacing the stock shocks on the Twin Cam Softail chassis.
They are specifically engineered to provide a better ride quality, reduced bottoming-out, and crucial ride-height adjustability that the stock setup lacks.
Progressive 422 Series Shocks for Harley Softail (2000-2017)
The 422 Series is an adjustable, high-performance coil-over shock system that replaces the stock horizontal-mounted shocks beneath the transmission.
Key Features
Ride-Height Adjustability (Slam-It Kit): This is the key selling point. The 422 Series allows you to easily adjust the rear ride height, offering up to 2 inches of lowering from the stock height. This is crucial for riders who want a slammed, custom look without permanently compromising handling.
Note: The adjustment is typically made via a simple threaded cam system (depending on the exact sub-model of the 422).
Improved Damping: The shocks use a high-pressure gas-charged monotube design. This provides consistent, fade-resistant damping and much better control than the stock oil-filled shocks, translating to a smoother and more stable ride, especially over freeway expansion joints and rough pavement.
Progressive Wound Springs: The springs are designed with a progressive rate, meaning they are softer initially for a comfortable ride over small bumps and rapidly increase in stiffness to prevent harsh bottoming-out.
Adjustable Preload: The spring preload is easily adjustable to compensate for the weight of a passenger, luggage, or changes in riding style, ensuring the shocks are always set optimally.
Direct Bolt-On: They are designed as a direct replacement for the OEM units located under the bike, often making installation straightforward.
Aesthetics: Available in popular finishes like Chrome and Black.
Fitment and Models
These shocks are a direct fit for the Twin Cam Softail models from 2000-2017, including:
Fat Boy (FLSTF)
Heritage Softail Classic (FLSTC)
Softail Deluxe (FLSTN)
Softail Standard (FXST)
Breakout (FXSB)
Blackline (FXS)
Why Choose the 422 Series?
Aesthetic Flexibility: The ability to easily adjust the ride height (from stock down to slammed) gives you the option to change the bike’s stance without buying new shocks.
Performance vs. Style: They offer a much better balance of performance and aesthetics compared to fixed-length lowering shocks, as you can still dial in better ride quality and cornering clearance when needed.
Load Rating: The 422s are typically available in Standard Duty (for loads up to ∼225 lbs.) and Heavy Duty (for loads over ∼225 lbs. or aggressive riding). Choosing the correct load rating is essential for the best performance.
