2.5 VS PB CDCV Rear Shocks (Pair) | 2021+ F150

Huge Improvement in Heat Dissipation and Off-Road Performance with Compression Adjustability When a standard internal reservoir rear shock just isn't enough to handle the extreme applications you have in mind for your 2004-2023 F150, you can turn to our friends over at ICON and their 2.5 VS Series Piggyback Reservoir rear shock to get the kind of rear suspension performance you need. This pair of powerful rear shocks offer up unprecedented levels of heat dissipation and heat resistance thanks to their massive oil capacities and aluminum designs, making them perfectly suited to constant and extreme articulation off-road. The Piggyback reservoirs even feature ICON's Compression Damping Control Valve (CDCV) system that allows you to dial in the shocks' compression perfectly to your liking.
