Fox 2.0 Performance Series IFP Rear Shocks 1999–2019 GM 2500HD/3500HD 0–3″ Lift

Upgrade your suspension with the proven performance of FOX 2.0 Performance Series IFP shocks. Engineered with race-proven damping technology, these shocks are designed to transform the ride quality of your truck or SUV by delivering a smooth, controlled on-road feel with predictable handling in even the toughest off-road conditions. The precision impact-extruded aluminum body increases cooling capacity while resisting corrosion, ensuring long-lasting durability. Inside, FOX’s Internal Floating Piston (IFP) mono-tube design separates shock oil from the high-pressure nitrogen gas chamber, eliminating aeration and maintaining consistent performance. Combined with a high-flow damping piston and application-specific valving, these shocks provide a balanced, responsive ride capable of handling rough terrain without sacrificing everyday comfort.
