FOX 2.5 Performance Smooth Body HTO 6.5 inches Front Lift IFP Shocks for 2020-2024 Chevrolet Silverado 3500HD

Part Number: 987-24-024

Summary: The FOX 2.5 Performance Series HTO shocks are engineered to provide enhanced on and off-road performance for lifted heavy-duty applications. Featuring an Internal Floating Piston (IFP) and a large 2.5-inch aluminum body, these shocks are designed to manage heat and provide consistent damping under load. This specific HTO configuration utilizes position-sensitive rebound control to mitigate harsh top-outs, making it an ideal solution for vehicles equipped with heavier aftermarket tires and raised torsion systems.

Features

• Internal Floating Piston (IFP): The internal mono-tube design separates shock oil from the high-pressure nitrogen gas chamber to provide consistent, fade-free damping performance.
• Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping to ensure reduced top-out harshness and increased comfort during extension.
• Anodized Aluminum Body: The 2.5-inch 6061-T6 impact-extruded aluminum construction provides high heat dissipation and corrosion resistance to ensure long-term durability.
• High-Flow Damping: Velocity-sensitive valving paired with a 5/8-inch hard chrome shaft provides rapid response to terrain changes to ensure improved vehicle stability.

Technical Specifications

Fitment

• 2020-2024 Chevrolet Silverado 3500HD
• Note: Lift: 6.5 inches. For Use With Raised Torsion Systems That Require Lower Eyelet Mounting. Will Not Fit OE Mounts.

What’s Included

• Includes 2 Shocks

Why Choose This Product?

• Engineering Advantage: The 2.5-inch aluminum body offers significantly more oil capacity and heat dissipation surface area than standard 2.0 shocks, while the HTO piston specifically manages the increased mass of heavy wheel and tire packages.
• Performance Benefit: Drivers experience a more controlled ride with a significant reduction in the “clunk” or harshness often associated with suspension top-out on lifted torsion-bar trucks.

Frequently Asked Questions

What is the benefit of the 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 improving comfort on lifted vehicles with heavy tires.

Will these shocks fit my stock height Silverado 3500HD?
No, these shocks are specifically designed for vehicles with a 6.5-inch front lift and require a raised torsion system that utilizes a lower eyelet mount.

What does the Internal Floating Piston (IFP) do?
The IFP separates the shock oil from the high-pressure nitrogen gas, which prevents oil aeration (foaming) and allows the shock to provide consistent damping performance in various conditions.
