Ford F150 Tremor Coilover Suspension Kit - Rear - ICON - 2.5 Series VS PB CDEV - `21-`23. This rear coilover pair is a vehicle-specific ICON 2.5 Series setup with piggyback reservoirs and the CDEV electronic compression valve for in-cabin tuning.

Built for the 2021-2023 F-150 Tremor 4WD, these ICON V.S. 2.5 Aluminum Series shocks are length- and valving-matched to the application and deliver improved control both off-road and on pavement. The piggyback reservoir design improves heat dissipation and creates an internal "Bump Zone" that increases damping by approximately 20% near full compression to help control high-speed compressions and reduce harsh bottom-outs. The included CDEV (Compression Damping Electronic Valve) lets you adjust compression settings from inside the truck and can be integrated with ICON Intelligent Control and the ICON mobile app (iOS device required). Shocks are 100% rebuildable and revalveable.
