Shock 2.0 IFP Rear 99-On Chevy HD 0-1in Lift

The FOX Shock 2.0 IFP Rear for 1999–2018 Chevy HD is engineered for heavy-duty truck owners who demand performance-level damping without excessive lift. This monotube shock absorber delivers the balance that modern HD owners need: responsive handling, refined comfort, and the ability to support lifted trucks within a modest 0–1 inch elevation range. Whether you're running stock geometry or planning a conservative suspension upgrade, this rear shock provides the tuning sophistication that separates OEM-equivalent units from true performance components.

Built with FOX's proven Isolated Floating Piston (IFP) technology, the Shock 2.0 IFP uses a monotube design with a sealed internal piston that isolates the nitrogen charge from the main damping circuit. This separation prevents aeration and fade under sustained high-temperature operation—critical for towing and hauling. The aluminum body with clear anodize finish resists corrosion while minimizing weight, and the smooth external design integrates cleanly into existing suspension geometry.

This shock pairs seamlessly with 1999–2018 GM full-size truck platforms including Silverado HD and Sierra HD models. Technicians and DIY enthusiasts will appreciate the independent tuning of compression and rebound damping curves, ensuring predictable response whether you're loaded or unloaded. Rear shocks are sold individually, so confirm your application requires replacement of a single rear unit or purchase as a pair for matched handling.
