Fits 2020-2026 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD (0-1" Lift).

The Fox 2.0 Performance Series IFP (Internal Floating Piston) rear shock delivers bolt-on performance for your heavy-duty truck, significantly improving both off-road control and on-road comfort. This shock features a metal-impacted aluminum body that dissipates heat four times faster than conventional steel shocks, preventing fade during heavy towing or aggressive trail use. The internal floating piston architecture separates the shock oil from the high-pressure nitrogen gas, eliminating oil aeration and ensuring consistent damping regardless of the terrain.

• Performance Body: 2.0-inch metal-impacted aluminum body with a clear-anodized finish for superior heat dissipation and corrosion resistance.
• Internal Floating Piston (IFP): Mono-tube design separates oil from high-pressure nitrogen gas to prevent cavitation.
• High-Flow Piston: Race-developed high-flow manual piston for predictable valving.
• Durable Components: Black-anodized, CNC-machined 6061-T6 aluminum components and heat-treated spherical bearings.
• Long-Life Seals: Redundant sealing pack system including main seal, wiper seal, and scraper seal.
