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

Part Number: 987-24-032

Summary: The FOX 2.5 Performance Series HTO shocks are engineered to provide a significant upgrade in damping capacity for the Chevrolet Silverado 3500HD. These shocks utilize an Internal Floating Piston (IFP) to separate shock oil from high-pressure nitrogen, ensuring consistent performance by preventing aeration. Designed specifically for front applications with 4-6 inches of lift, they feature Hydraulic Top Out (HTO) technology to manage rebound damping and eliminate harshness during suspension extension.

Features

• Internal Floating Piston (IFP): The internal floating piston (IFP) separates the shock oil from the high-pressure nitrogen provides optimized damping to ensure consistent performance by preventing oil aeration.
• Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping control to ensure reduced harsh top-outs and increased comfort when running heavier tires.
• Impact Extruded 6061-T6 Aluminum Body: A 2.5-inch Type II clear-anodized aluminum body provides efficient heat dissipation and corrosion resistance to ensure durability in harsh environments.
• High-Flow Velocity-Sensitive Damping: Vehicle-specific valving and larger pistons provide increased damping capacity to ensure improved on and off-road performance.

Why Choose This Product?

• Engineering Advantage: The combination of an Internal Floating Piston (IFP) and Hydraulic Top Out (HTO) technology allows for precise, position-sensitive rebound control that standard shocks cannot provide.
• Performance Benefit: Drivers experience a reduction in harsh suspension top-outs and improved thermal management, resulting in a more controlled and comfortable ride on lifted applications.

Frequently Asked Questions

What does the Hydraulic Top Out (HTO) technology do?
HTO technology reduces harsh top-outs by forcing shock oil through a secondary shim stack, which slows down the shock shaft speed during rebound.

Are these shocks compatible with all lift kits?
No, these shocks are specifically noted to not be for use with lift kits that change the original equipment (OE) mounts.

What is the benefit of the aluminum body?
The 2.5-inch impact extruded 6061-T6 aluminum body is designed to dissipate heat more efficiently than traditional steel bodies while preventing corrosion.
