Progressive Suspension 444-4074B Black 13.5″ Harley Shocks

Our 444 series shocks feature a proprietary patented frequency Sensing technology (fst) that has the unique ability to dynamically adjust damping as you ride; what this means is whether you’re hitting the small or Big bumps in the road, the shock distributes oil through ports accordingly to soak up the hit making for an ultimately comfortable ride. A top mount threaded preload adjuster allows for fine-tuning with a simple twist of the cap. 444 series shocks are available in 3 configurations: standard (up to 250 lbs.), heavy-duty (250+ lbs.) and Super heavy duty (touring models only – 350+ lbs.).
