Progressive Suspension  444 Series FST Shocks For Harley Dyna

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 12" to 13.3"
  • 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

Fitment Notes & Exceptions

  • Not for Switchback (FLD) models
  • To use the 11.5” shocks on FXDWG models, the fender may need to be modified as follows: When the shock is compressed, the belt guard may hit the fender edge (see Figure 1). Trim the fender as shown in Figure 1 inset. After trimming is complete, install shock and compress to verify that belt guard clearance is sufficient.

This product is a big improvement over stock shocks!!! The riding comfort on my 2014 Super Glide has improved remarkably, as well as the handling. No more bottoming out over bumps and speed humps. My spine also thinks these Progresive shocks are great. Lee Forsythe July 27, 2015
Great upgrade from stock I was advised to get the standard 13" 444s after talking to the pros at Progressive customer service, then went straight to Revzilla to buy them. While these do require a lot of trial and error to find your sweet spot (there's no presets or reference points to help you) they are an amazing upgrade from stock. Progressive suggested a sag of 3/4". Even at the lightest setting my sag is 1/2" and I weigh 230 & don't ride with luggage or carry a passenger on the back. So be careful if your'e considering getting the heavy duty 444s you might find them too stiff and unable to adjust to your comfort level. June 29, 2015
Excellent upgrade from stock. These Progressive 444's made a big difference in handling on my 2009 FXDC. Also added Ricor Inertia active vales to the stock front fork. The combination helped turn the cruiser into a competent sports tourer. October 13, 2014

Steven S: Go with heavy duty if you're over 200 lbs, ride two-up a lot, pack heavy, or just want a stiff ride. I'm 150 lbs and got the standards. They're great, a noticeable improvement over stock. Also added Ricor Inertia Active Valves to the stock front springs. 2009 FXDC handles like it should in the twisties and everywhere else!

Neil M: I bought the 1 inch longer shocks for my Dyna Fat Bob 2014 middle of last year. Set on the standard setting they are firmer than stock, handle better and are stiff enough to have a tour two up with luggage without adjusting to a stiffer setting. The positive is, no more exhaust scrapping and in combination with shorter front pegs (with a 45deg cut) it can slice through roundabouts etc easy without touching ... just a firmer ride but still acceptable for a cruiser ... in my opinion! I don`t think there was an option of normal or Heavy duty at the time? The bike steers a bit quicker now as well so that a bonus! I hope this helps Apr 6, 2015

A shopper asked: I weigh 250 lbs, no 2 up riding and no carrying luggage. Should I get the regular or HD springs ? I'm looking for good handling and a smooth ride. Harry Apr 30, 2014

Toby F: I weigh 240 and ride a 2014 Street Bob with progressives 444(regular springs ). Ride is great. May 2, 2014

Brian K: I weigh about 215 lbs. and don't carry much in terms of gear and only ride solo - the standard rate springs on the 12 inch (stock length for my 2011 FXDB) 444s are fine. When I installed the shocks and measured to adjust for ride sag, it turned out I didn't need to adjust for any preload. I have the recommended 1 inch sag with the collar all the way up (maximum counter clockwise position). Went for a ride right after installing and purposely went over every "imperfection" in the road and never bottomed out and found the suspension to be so much smoother than the stock shocks.

James P: I weigh 170 without gear on and little to no 2 up riding and I ride with the hd on the softest settings. It's superior to the factory ride quality still. I would do the hd if I were you. Whenever I upgrade, if I do the progressive specifically the 444, they will be hd as well. May 1, 2014
