Smooth out the bumpiest bumps with FOX 2.0 Performance Series Smooth Body IFP Reservoir Shocks. Featuring an external reservoir that separates and makes space for additional shock oil and high-pressure nitrogen, these shocks look and run super cool. Plus, with 2 in. diameter aluminum bodies, 5/8 in. hard chrome-plated heat-treated alloy steel shafts and IFP (internal floating pistons), FOX smooth body reservoir shocks transform your rigs on- and off-road performance. Metal-impacted 6061-T6 aluminum bodies dissipate heat fast. Vehicle-specific valving maximizes on- and off-road performance while delivering a predicable ride quality. And, the direct replacement mounting design bolts right onto stock height trucks and rigs with aftermarket lifts kits. With built-in factory performance, FOX IFP Reservoir Shocks can also be fine-tuned with full adjustability of nitrogen pressure, and compression- and rebound-valving (must be factory serviced).
