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