ICON 67811P 4.5" Front 2.5 VS RR Shocks Pair for 23-25 Ford F250/F350 SD 4WD

23-25 FSD 4.5" FRONT 2.5 VS RR PAIR ICON’s 2.5 Aluminum Series shocks are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. With a truly vehicle-specific design, these shocks are configured specifically for each application in both length and damping tune. Featuring one-piece impact extruded aluminum cylinders, these 2.5 Aluminum Series shocks offer lighter weight, improved corrosion resistance, and a more uniform finish than traditional plated steel cylinders. Like all ICON shock absorbers, these 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. Remoyte reservoirs greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. 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-out conditions and controls the suspension effectively when compressing at high velocity. If you are looking for a more user-defined tune, consider looking into the Compression Damping Control Valve (CDCV) shocks. Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range Nitrogen charged monotube design with remote reservoir Remote reservoirs maintain cooler operating temperatures during extended off-road use and allow for longer suspension travel One-piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road 7/8” diameter induction hardened, chrome plated shock shaft
