Progressive 444 Series Shocks For Harley Big Twins

After more than a decade of ruling the roads with the road proven 440 Series shocks, Progressive 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.

Features:

  • Frequency Sensing Technology (FST) allows the shocks to sense the frequency of a bump and automatically adjust damping for superior ride quality
  • Deflective disc valving
  • Adjust spring pre-load by hand - no special tool needed!
  • Progressive-rate spring
  • Made in USA
View Fitment Notes & Exceptions

Fitment Notes & Exceptions

  • Stock shock length varies from vehicle to vehicle - please verify your length prior to ordering
  • Shock lengths are measured fully extended, eyelet-to-eyelet on centers
  • Changing ride height can potentially change many carefully-engineered attributes of your bike, including trail and mechanical trail
  • A change in ride height at one end of the vehicle usually will require a change at the other end
  • 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 - common interference spots include swingarm, axle, frame, tire, fender, chain/belt and guard, and exhaust
  • For 1985 and earlier applications, these shocks will fit 4-speed frames only - please verify transmission before purchasing
