ICON 97721XP 21-24 F150 4WD TREMOR Rear 2.5 VS PB CDXS PAIR

21-25 F150 4WD TREMOR REAR 2.5 VS PB CDXS PAIR ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks with CDCV are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. These shocks are configured specifically for each application in both length and damping tune. Like all ICON'S Shock Absorbers, V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. For piggyback and specific remote reservoir applications, ICON'S unique use of a 6061 billet aluminum manifold a few inches below the top cap of the shock creates an internal Bump Zone that when used creates an additional 20% of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity. ICON's exclusive Compression Damping Dual Speed (CDXS) valves are included for precisely dialing in your suspension performance. CDXS controls fluid flow under compression, with independent adjustability of high speed and low speed compression force. 10 discreet detented settings for both low and high-speed adjustment knobs allow separate adjustments for handling response and overall aggressiveness. ICON CDXS equipped for independent adjustability of high speed and low speed compression force for handling response and aggressiveness ICON’s internal “Bump Zone” increases damping by 20% to provide more control as the shock approaches full compression Nitrogen charged monotube design with piggyback reservoir Piggyback reservoir design improves heat dissipation to reduce shock fade during prolonged use Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range
