Part Number: 987-24-030

Summary: The FOX 2.5 Performance Series HTO shocks are engineered to enhance both on and off-road performance for the GMC Sierra 3500HD. Featuring an Internal Floating Piston (IFP) and position-sensitive technology, these shocks address the need for improved damping capacity and heat dissipation. The application of Hydraulic Top Out (HTO) technology provides controlled rebound damping, specifically designed to reduce harsh top-outs and increase ride comfort.

Features

• Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping to ensure reduced harsh top-outs and increased comfort.
• Internal Floating Piston (IFP): The 2.5-inch shock body separates shock oil from high-pressure nitrogen to ensure optimized damping performance.
• Aluminum Body: Impact extruded 6061-T6 aluminum with Type II clear-anodized plating provides efficient heat dissipation to ensure corrosion resistance and consistent cooling.
• High-Flow Damping: Velocity-sensitive valving and larger pistons provide increased capacity to ensure improved control under varying terrain.

Frequently Asked Questions

What is the benefit of Hydraulic Top Out (HTO) technology?
HTO technology uses a secondary shim stack to slow down shock shaft speed, which reduces harsh top-outs and increases overall ride comfort.

Are these shocks designed for lifted vehicles?
Yes, these shocks are specifically configured for vehicles with a front lift height of 0 to 1 inch.

How does the Internal Floating Piston (IFP) improve performance?
The IFP separates the shock oil from the high-pressure nitrogen, which optimizes damping by preventing aeration and ensuring consistent performance.
