Fox 2.0 Performance Series IFP Front Shock for 2020-2026 Chevrolet/GMC 2500/3500 HD, 0-1" Lift (985-24-238)

Fits select 2020-2026 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD models.

The Fox 2.0 Performance Series IFP (Internal Floating Piston) front shock is engineered to transform your heavy-duty truck's suspension performance. This bolt-on upgrade provides increased off-road capability by extending drop-out travel while maintaining precise on-road handling. The vehicle-specific valving is designed to reduce body sway and provide a more connected feel, whether you are navigating technical trails or towing on the highway.

Constructed with a 2.0-inch metal-impacted 6061-T6 aluminum body, these shocks dissipate heat four times faster than conventional steel shocks to prevent performance fade. The internal floating piston (IFP) design mono-tube architecture separates the shock oil from the high-pressure, nitrogen-charged gas chamber, eliminating oil aeration for consistent damping in harsh environments. Each shock is 100% serviceable and tunable, ensuring a long service life on your HD rig.
