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.

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.

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.

throw away your factory shocks
Put a set of these on my '08 FXDB I weigh 205, no more bottoming out on potholes. No more mushy feeling when you
hit the gas. Far better ride and overall performance than the OEM shocks...

The only reason I am keeping my old shocks is if ever I get another bike these will fit, they are coming with me....

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.

Major improvement in stability and Handling
I had never upgraded from stock before on my other bikes. These shocks are awesome. Right out of the shop I noticed the improved ride. Wife jumped on the back, I dampened the setting, and what a noticeable difference with my DWG in stability and handling.

Great shocks
install was pretty easy. Needed a vice to insert the provided bushings. Only issue was the stock bolt cover on my 2016 Street Bob would not fit back over the top of the new shock bolting location.

I'll never go back to stock
I bought these in 13" and put them on my '09 Street Bob probably about 10k miles ago. ....I should have done this from the start.
I have a sundowner seat. That seat and the shocks make for a very nice, comfortable ride. Yet firm enough to feel planted taking corners...faster than I should.

I since sold the Street Bob and bought the Low Rider S and the 444's were transferred to the new ride. As long as I have a Dyna I will have the 444's.

....if only they made it in 13.5" or 14".

What size of this 444 series will fit best on my 2001 Harley Dyna FXD? I want to buy them but need to know what size please? Thank you! Roger G.
Roger G on Mar 9, 2016
My rider weight plus passenger s 205kg or 452lbs. My new stock shock bottom out easily.?
A shopper on Jul 12, 2016
BEST ANSWER: I replaced my standard shocks on my 2009 Fat Bob which are 12" long with the heavy duty 13" 444 shocks to improve ride and ground clearance on cornering. My weight is 105 +46 for wife.
The ride is a lot better, my wife can't feel bumps that she complained about prior to fitting them, they are a lot better then the standard and even after riding over some bumpy sections on deliberately found they were good and rear tyre kept good traction. I would recommend the heavy duty shocks.
As for the ground clearance, I have V&H super radius pipes that would scrap easy on tight corners, I have pushed the bike as hard as I can and have not been able to scrap them. The bike does sit about 40mm higher measuring tyre to guard.
Would recommend changing the front forks to if you like to ride hard, I replaced with the HD upgrade and found the ride a lot better, especially during hard braking, the standard were too soft and nose dived, new ones keep the bike level.
After reading a number of forums I also replaced my standard tyres with Avon Cobra's, I went up in size to 200 x 60 with standard size front. I can confirm that the tyre fits without any mods to the bike. I have done about 3,000klm now and pushed them hard on some mountain roads and can't fault them, they a heaps better then standard tyres.
If you want a HD that you can throw around in the corners and has a good ride I can recommend the changes.
Whats the difference between Standard and Heavy Duty?
Clifford B on Apr 5, 2015
BEST ANSWER: 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!

Steve, Santa Fe, New Mexico
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
A shopper on Apr 30, 2014
BEST ANSWER: I weigh 240 and ride a 2014 Street Bob with progressives 444(regular springs ). Ride is great.
They don't come in 11inches ?
Mohamed H on Jun 4, 2016
BEST ANSWER: part # you want is 444-4005(B- Black, C- chrome)
I have bags on my 2011 Super Glide and to top of the shock is blocked by the bags. Can these be mounted upside down?
Robert D on Sep 5, 2016
BEST ANSWER: According to the spec's no, but their is another model that can be mounted upside down.
Send an email to the customer service sight like I did to get more info.

Terry.
