FOX 2.5 Performance Smooth Body HTO 4-6 inches Rear Lift IFP Shocks for 2011-2019 Chevrolet Silverado 3500HD

Part Number: 987-24-035

Summary: The FOX 2.5 Performance Series HTO shock is a bolt-on solution designed specifically for the Chevrolet Silverado 3500HD. This series utilizes position-sensitive technology and an Internal Floating Piston (IFP) to separate shock oil from high-pressure nitrogen, which optimizes damping for both on and off-road environments. Constructed with a Type II anodized aluminum body, these shocks are engineered to dissipate heat efficiently while providing enhanced rebound control for vehicles with 4-6 inches of rear lift.

Features

• Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping control to ensure reduced harsh top-outs and increased comfort.
• Internal Floating Piston (IFP): The internal piston separates shock oil from high-pressure nitrogen gas to ensure optimized damping and consistent performance.
• Aluminum Body: A 2.5-inch 6061-T6 impact extruded aluminum body provides efficient heat dissipation and corrosion resistance to ensure long-term durability.
• Hard Chrome Shaft: A 5/8-inch hard chrome plated heat-treated alloy steel shaft provides increased strength to ensure reliable operation under load.

Frequently Asked Questions

What is the benefit of the HTO technology?
Hydraulic Top Out (HTO) technology reduces harsh top-outs by forcing shock oil through a secondary shim stack, slowing the shock shaft speed for better comfort.

Does this shock help with heat management?
Yes, the 2.5-inch impact extruded 6061-T6 aluminum body is designed to dissipate heat more efficiently than traditional steel bodies.

Is this shock compatible with a stock height truck?
No, these shocks are specifically designed and valved for Chevrolet Silverado 3500HD models with 4-6 inches of rear lift.
