Product Details

Fox 2.0 Performance Series IFP single front coilover shock matched for the Cognito 4-6 Inch lift kit for 07-18 Chevrolet and GMC 1500 2WD/4WD Trucks and SUVs. Not compatible with 2007 Classic body style models (2007 Classic style compatible with 99-06 model components).

This Bolt-on, Performance Series Coil-over IFP shock is loaded with advanced technology and a long list of features that set it apart. The precision, metal impact extruded aluminum body increases cooling capacity and is rust resistant. The vehicle-specific upper mount includes a composite bushing that isolates noise and vibration.

Locking, spring preload rings that allow easy ride height and preload adjustment retain a top quality racing coil, selected to deliver the optimal spring rate.

Performance Series Coil-Over IFP shocks bolt on with no modifications and are designed to level your truck front-to-rear. Applications are available for stock and lifted trucks that re-use the stock shock.

Inside is an internal reservoir with Internal Floating Piston (IFP) mono-tube design separates the shock oil from the high-pressure, nitrogen-charged gas chamber. The IFP eliminates oil aeration allowing maximum performance from the factory-tuned, precision valving.

The easy-to-install, 2.0 Performance Series Coil-over IFP provides a comfortable on-road ride and predictable off-road handling in even the toughest conditions.
