FOX 2.5 Performance Smooth Body HTO 1.5-2.5 inches Rear Lift IFP Shocks for 2011-2024 Chevrolet Silverado 3500HD

Part Number: 987-24-011

Summary: The FOX 2.5 Performance Series HTO shocks are engineered to enhance both on and off-road performance for the Chevrolet Silverado 3500HD. Featuring a 2.5-inch impact extruded 6061-T6 aluminum body, these shocks utilize an Internal Floating Piston (IFP) to separate shock oil from high-pressure nitrogen, ensuring consistent damping. The integration of Hydraulic Top Out (HTO) technology provides position-sensitive rebound control, specifically addressing the harsh top-outs often experienced with heavier tires or lifted applications.

Features

• Internal Floating Piston (IFP): The internal floating piston (IFP) separates the shock oil from the high-pressure nitrogen to provide optimized damping and prevent oil aeration.
• Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping control to slow down shock shaft speed and reduce harsh top-outs.
• 6061-T6 Aluminum Body: The 2.5-inch impact extruded aluminum body with Type II clear-anodized plating provides efficient heat dissipation to ensure corrosion resistance and sustained performance.
• Chrome Shaft: A 5/8-inch hard chrome shaft provides durability and strength to ensure long-term operation under demanding conditions.

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, which slows down the shock shaft speed for increased comfort.

Does this shock help with heat management?
Yes, the 2.5-inch 6061-T6 aluminum body is designed to efficiently dissipate heat and prevent corrosion during operation.

What lift height are these shocks compatible with?
These shocks are specifically designed for vehicles with 1.5 to 2.5 inches of rear lift.
