Product Details

Progressive Suspension  444 Series FST Shocks For Harley Sportster & FXR

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.

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
  • Sold as a pair
  • Made in USA

Notes:

  • Depending on model, your stock shock length is 11" 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
Made in the USA

Built for adventure
Upgraded front and rear with progressive suspension and I couldn't be happier. Simple install, both front and rear-if I can do it, you can do it. Better handling, smoother, built for adventure and comfort. yeah buddy

LOVE AT FIRST RIDE
I am a guy who normally don't write reviews however I drive a 2008 Harley XL1200C and purchasing the Progressive 444's definitely was the best upgrade I could put on. I notice a huge difference in comfort and is truly love at first ride. I highly recommend this to everybody who rides!

Night and Day
I upgraded both the front and rear suspension to Progressive HD fork springs, as well as Progressive HD 444 in the rear. The stock suspension is jarring to the point where small bumps feel like craters. The new Progressive suspension made the ride so much more enjoyable.

ages better but still...
This suspension is great! Its a huge boost in comfort.
They look absolutely nice and the ride is ages better than the original. Before the bike was getting upset by every little crack in the black top. now at freeway speeds my little sporty runs nice and straight... perfect for cruising/traveling/commuting.

anyway, it might be because i am coming from Ducatis and Dirt bikes with tuned suspension i was hoping for more but do not expect a Harley to suddenly ride nice or handle well just by switching out the shocks.
Even with the best shocks a 500 brick of iron stays a 500 pound brick of iron and trying to ride the bike faster around a corner is sill very much like trying to tame a mechanical bull in a country bar... a lot of fun but it gets really tiring after a few miles...
