Progressive Suspension 444 Series FST Shocks For Harley Tri-Glide

Progressive has unveiled another groundbreaking design with their 444 Series FST Shocks. The FST or Frequency Sensing Technology features an unmatched ability to dynamically adjust damping while riding. The result is superior performance no matter the road conditions. A top-mounted, threaded preload adjuster allows for fine tuning with a simple twist of the cap.

Features:

Frequency Sensing Technology (FST) allows the shocks to sense the frequency of a bump and automatically adjust damping for superior ride quality
Adjust spring pre-load by hand - no special tool needed
Progressive-rate spring
Deflective disc valving
13 1/2" length
Sold as a pair
Made in USA

Notes:

Stock shock length is 13"- These are 1/2" longer to allow for a smoother ride
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
