Progressive Suspension 412 Series Shocks For Harley Sportster & FXR

The 412 Series shocks are simply the best value shock the Progressive offers. The 412's simple, durable design means they will be an improvement to your motorcycle's suspension performance for as long as you are riding it. The double-wall steel body construction with nitrogen charged, multi-staged velocity-sensitive valving gives you smooth, consistent damping. A five position cam-style preload adjuster lets you dial in your ride whether you're a light rider or heavy hitter. Step into suspension that works for you.

Features:

• Nitrogen-charged
• Cam-style preload adjuster
• Sold as a pair
• Made in USA

Notes:

• Depending on model, your stock shock length is 11 1/2" to 13 1/2"
• Shock lengths are measured fully extended, eyelet to eyelet on centers
• A change in height at one end of the bike may require a change at the other
• Changing ride height can potentially change the trail and mechanical trail
• Heavy Duty shocks are recommended for bikes operated at or near the OEM maximum load rating over 50% of the time
• Prior to purchasing shocks that are different than your OEM length, please verify that wheel and suspension travel can be altered without causing clearance issues to the swingarm, axle, frame, tire, fender, chain/belt and guard, and exhaust
