🧾 Overview
The FOX Performance Series 2.0 IFP Rear Shock is a major upgrade for Jeep Wrangler JK owners seeking improved control, durability, and fade resistance without sacrificing on-road comfort. Built around FOX’s Internal Floating Piston (IFP) mono-tube design, this shock separates oil from high-pressure nitrogen to maintain consistent damping under hard use.
With a 2.0-inch aluminum body that dissipates heat far better than steel shocks, the FOX 2.0 dramatically reduces fade during extended trail runs while delivering a smooth, predictable ride on the street. Application-specific valving and a 5/8” chrome-hardened shaft provide excellent off-road performance without harshness—making it a strong step up from factory and many “white-body” lift shocks.
✔ Huge performance increase over stock shocks
✔ IFP design reduces fade and improves consistency
