Fox 2.5 Performance Series Smooth Body IFP HTO Front Shock, 0-1" Lift for 2011-2019 Chevy/GMC 2500/3500 HD

Fits 2011-2019 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD models.

The Fox 2.5 Performance Series Smooth Body IFP HTO shock is designed to improve off-road capability while maintaining refined on-road handling for heavy-duty trucks. Built with a massive 2.5-inch impact-extruded 6061-T6 aluminum body, this shock dissipates heat four times faster than traditional steel alternatives, ensuring consistent, fade-resistant damping during prolonged use. The internal floating piston (IFP) separates the high-pressure nitrogen gas from the oil, preventing aeration and ensuring the velocity-sensitive valving performs reliably under any terrain conditions.

This specific model includes Fox's Hydraulic Top Out (HTO) piston, which provides a controlled deceleration as the shock reaches full extension, protecting your suspension components during aggressive driving. Fully rebuildable and re-tunable, these shocks are an investment in long-term vehicle performance and durability.

• Internal Floating Piston (IFP): Monotube design keeps gas and oil separate to eliminate aeration.
