Fox Racing Shocks 985-02-158 Performance Series Coilover IFP Shock - 2.0

The Fox Racing Shocks 985-02-158 is a Fox 2.0 Performance Series Coilover IFP shock engineered for truck and SUV applications demanding superior on- and off-road suspension performance. Part of Fox's renowned 2.0 Performance Series lineup, this coilover shock delivers race-derived technology in a direct bolt-on package with no modifications required.

At the core of this shock is a mono-tube Internal Floating Piston (IFP) design that separates the shock oil from a high-pressure nitrogen gas charge. This eliminates oil aeration and ensures consistent, fade-free damping performance whether on the street or the trail. The factory-tuned precision valving delivers a balanced ride that is compliant on pavement and controlled in the rough.

The shock body is constructed from precision metal impact-extruded aluminum, which dissipates heat faster than steel and resists rust and corrosion. A clear anodized finish provides additional protection in wet and salty environments. The vehicle-specific upper mount features a composite bushing to isolate noise and vibration from the cabin.

Locking spring preload rings allow easy ride height and preload adjustment, retaining a top-quality racing coil selected for the optimal spring rate. The unit arrives preset and ready for installation straight out of the box.
