PROGRESSIVE SUSPENSION - 31-5056 - Fork Preload Adjuster - 49 mm - Black Anodized
Progressive Suspension has been engineering premium American-made shocks for V-twin and cruiser motorcycles for decades, and the 31-5056 continues that tradition with a design built for street, touring, and custom riding. Great thread-in solution to improve front suspension performance, so the suspension automatically adjusts damping based on shock speed — firm under hard hits, compliant over slow, rolling bumps. Add preload to stiffen up the front fork for aggressive riding in the canyons. Decrease preload to soften the suspension for a day of comfortable cruising. The ability to change preload settings also provides improved front suspension performance when going from a single rider to a rider with passenger configuration. Allows the user to custom tune the front suspension for any riding condition. Pair with a Progressive Suspension Fork Spring Kit to maximize riding performance. Available in multiple fitments and configurations — check the application guide to confirm the right length and spring rate. Sold individually.
