Description
Pick up the Icon 37705P 2.5 VS Piggyback Shock Absorber (Pair) from RDP for your 1999-2016 Ford F-250/350 4WD (Rear Lifted 0-3″) today. Icon’s 2.5 Aluminum Series shocks are designed to deliver exceptional performance both off-road and on the street. These shocks are specifically engineered for your vehicle, with precise adjustments made to length and damping tune. Constructed from one-piece, impact-extruded aluminum cylinders, these 2.5 Aluminum Series shocks offer lighter weight, superior corrosion resistance, and a more consistent finish than traditional plated steel cylinders. Like all Icon shock absorbers, these shocks are fully rebuildable and re-valvable. For piggyback and specific remote reservoir applications, Icon integrates a 6061-billet aluminum manifold below the shock’s top cap, creating an internal “Bump Zone” that increases damping force by an additional 20%. This boost in damping helps prevent harsh bottom-outs and improves suspension control during high-velocity compression. If you’re seeking a more customizable experience, the Compression Damping Control Valve (CDCV) shocks provide adjustable tuning to suit your needs.
