444 Series Shocks feature Frequency Sensing Technology that dynamically adjusts 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.).
