FOX 2.5 Performance Smooth Body HTO 1.5-2.5 inches Front Lift IFP Shocks for 2020-2024 GMC Sierra 2500HD

Part Number: 987-24-010

Summary: The FOX 2.5 Performance Series HTO is a specialized bolt-on shock designed for the 2020-2024 GMC Sierra 2500HD. Engineered with an Internal Floating Piston (IFP) and a 2.5-inch aluminum body, this shock focuses on efficient heat dissipation and consistent damping performance. It features Hydraulic Top Out (HTO) technology to provide position-sensitive rebound control, specifically addressing the harsh top-outs often experienced with heavier tires or lifted applications.

Features

• Internal Floating Piston (IFP): An internal chamber separates shock oil from high-pressure nitrogen to provide optimized damping and prevent aeration.
• Hydraulic Top Out (HTO): A secondary shim stack slows shock shaft speed to provide position-sensitive rebound damping and reduce harsh top-outs.
• 6061-T6 Aluminum Body: Impact-extruded 2.5-inch aluminum construction with Type II clear-anodized plating provides efficient heat dissipation to ensure corrosion resistance.
• High-Flow Piston: Velocity-sensitive damping technology provides increased capacity to ensure improved on and off-road ride quality.

Why Choose This Product?

• Engineering Advantage: The use of a 2.5-inch large-bore aluminum body and Internal Floating Piston (IFP) technology allows for superior cooling and more consistent damping compared to standard steel-body shocks.
• Performance Benefit: Drivers benefit from Hydraulic Top Out (HTO) technology which mitigates the “clunk” of suspension topping out, particularly after adding heavier, aggressive tires.

Frequently Asked Questions

What is Hydraulic Top Out (HTO) technology?
HTO technology uses a secondary shim stack to slow down the shock shaft speed as it reaches full extension, reducing harsh top-outs and increasing comfort.

Do these shocks work with a lift kit?
Yes, these shocks are specifically designed for GMC Sierra 2500HD models with 1.5 to 2.5 inches of front lift.

What are the benefits of the aluminum shock body?
The 6061-T6 aluminum body dissipates heat more efficiently than steel and features Type II clear-anodized plating for corrosion resistance.
