Summary: The FOX 2.0 Performance Series shocks provide race-dominating performance in a hassle-free, bolt-on package specifically for the 2011-2018 Chevy Silverado 2500HD. These shocks utilize an Internal Floating Piston (IFP) to solve the common issue of oil aeration, ensuring predictable ride quality even in rough road conditions. The metal-impacted aluminum body is engineered to dissipate heat faster than traditional steel, maintaining consistent damping performance during rigorous use.

Features

• Internal Floating Piston (IFP): A high-pressure nitrogen gas chamber separates shock oil from gas to provide a predictable ride quality to ensure capability under the roughest road conditions.
• Aluminum Shock Body: Metal-impacted aluminum construction provides faster heat dissipation than conventional steel to ensure consistent performance and reduced fade.
• Nitrile Bushings: High-quality nitrile material provides increased articulation to ensure improved suspension movement and durability.
• Redundant Sealing System: A multi-layered seal design provides long-lasting protection to ensure sustained performance over time.
• Serviceable Design: 100 percent serviceable and tunable components provide a customizable experience to ensure a longer product lifespan.

Why Choose This Product?

• Engineering Advantage: The use of an Internal Floating Piston (IFP) eliminates oil aeration, which is a common failure point in standard shocks, while the black anodized CNC machined aluminum components provide superior heat management.
• Performance Benefit: Drivers experience a more controlled and predictable ride on both smooth and rough surfaces due to the vehicle-specific tuning and faster cooling properties of the aluminum body.

Frequently Asked Questions

Will these shocks work with aftermarket lift kit mounts?
No, these shocks are designed to work only with Factory OEM Mounts. They are not compatible with lift kits that modify the stock mounts, such as those from Rough Country.

What is the benefit of the Internal Floating Piston (IFP)?
The IFP separates the shock oil from the high-pressure nitrogen gas chamber, which prevents oil foaming and ensures consistent, predictable damping in rough conditions.

Are these shocks rebuildable?
Yes, the source documentation states these shocks are 100 percent serviceable and tunable for a longer lifespan.
