Fox Racing Shocks 987-24-011 Performance Series Smooth Body IFP HTO Shock - 2.5 Rear

The Fox Racing Shocks 987-24-011 Performance Series 2.5 smooth body shock delivers race-proven damping control and fade-free performance for lifted GM 2500/3500 trucks. Designed for 2011 and newer Silverado and Sierra HD models with 1.5 to 2.5 inch lift kits, this rear shock features advanced HTO (Hydraulic Top-Out) technology that provides superior control during suspension droop events, eliminating the harsh tugging sensation that occurs when wheels fully extend over rough terrain.

Key Features:

• 2.5 inch smooth bore zinc-plated seamless steel body for enhanced durability and corrosion resistance
• IFP (Internal Floating Piston) monotube design separates shock oil from high-pressure nitrogen to prevent aeration and maintain consistent damping
• HTO (Hydraulic Top-Out) technology with additional internal piston buffer for improved rebound control
• 7/8 inch hard chrome-plated heat-treated alloy steel shaft resists wear and corrosion
• Application-specific valving custom-tuned for GM HD truck weight and suspension geometry
• Larger oil capacity compared to 2.0 series provides improved heat dissipation and fade resistance
• Black-anodized CNC-machined 6061-T6 billet aluminum components

Fox Performance Series shocks bridge the gap between entry-level dampers and premium reservoir-equipped models, delivering professional-grade suspension control for both daily driving comfort and aggressive off-road use. The increased piston surface area and oil volume of the 2.5 series handle heavier loads and sustained high-speed terrain better than smaller diameter shocks, making this an ideal upgrade for work trucks and recreational vehicles that demand consistent, fade-free performance.
