Your cart is empty.After more than a decade of ruling the roads with the road proven 440 Series shocks, 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. Deflective disc valve. Adjust spring pre-load by hand, no special tool needed. Progressive rate spring. Standard spring rate and chrome finish.

Little stiff ride. The progressive tech weight estimations seem to be off. They recommended if the weight of two up riding was 250+ 50% of the time go with the HD shock. Should have gone with SD. I've set the SAG, rode over 1000 miles and now have the shock set at the softest setting and still to stiff.... even with a detachable tour pack. But the handling is awesome and wouldn't go back to the terrible air shocks that were standard on the bike.

Bought a 2015 street glide with air ride and boy what a rough ride was thinking it might have been a mistake. No matter were I adjusted the pressure just didn't work. Found these progressive 444 12inch heavy duty springs online and talked to an engineer at progressive and because I ride 2 up most of the time he said these would work. Well after riding 200 miles on the new shocks I have to say WOW !!! no more bone jarring jolts no more soar backs...Harley davidson should junk there air ride and think about these ...20 min install time.
