Progressive Suspension 444 Series FST Shocks For Harley V-Rod
After more than a decade of ruling the roads with the road proven shocks, Progressive Suspension unveiled another breakthrough design. Dubbed Frequency Sensing Technology (FST) for its unique ability to dynamically adjust damping as you ride. The result is superior performance no matter the road conditions. A top mount threaded preload adjuster allows for fine tuning with a simple twist of the cap.
- 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
- Sold as a pair
- Made in USA
- Depending on model, your stock shock length is approximately 13"
- 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
