Progressive Harley 444 Series Shocks 13.0in Super Heavy Duty - Black

The 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 Weight, Heavy-duty (250+ lbs.) and Super Heavy Duty (Touring Models only - 350+ lbs.).This Part Fits: Year Make Model Submodel 2021 Harley-Davidson FLH Electra Glide Revival Base 2023 Harley-Davidson FLHFB Electra Glide Highway King Base 1997-2016,2020-2022 Harley-Davidson FLHR Road King Base 2007-2016 Harley-Davidson FLHRC Road King Classic Base 1998-2006 Harley-Davidson FLHRCI Road King Classic Base 1996-1997,2000-2006 Harley-Davidson FLHRI Road King Base 2004-2007 Harley-
