Summary: The FOX 2.0 Performance Series Reservoir shocks provide race-dominating performance in a hassle-free, bolt-on package for the GMC Sierra 2500HD. Engineered with an External Reservoir system, these shocks are designed to dissipate heat rapidly during sustained operation. By utilizing an Internal Floating Piston (IFP) to separate oil from the high-pressure nitrogen gas chamber, these shocks ensure predictable ride quality even when handling the roughest road conditions.

Features

• External Reservoir System: External reservoir design provides increased oil capacity to ensure faster heat dissipation during high-speed operation.
• Internal Floating Piston (IFP): High-pressure nitrogen gas chamber provides a separation between oil and gas to ensure a predictable ride quality.
• Aluminum Body: Metal-impacted aluminum construction provides faster heat dissipation than conventional steel to ensure consistent damping performance.
• Nitrile Bushings: Durable nitrile material provides increased flexibility to ensure improved suspension articulation.
• Redundant Sealing System: Multi-layer seal configuration provides a robust barrier against contaminants to ensure long-lasting performance.

Frequently Asked Questions

What is the benefit of the External Reservoir?
The External Reservoir system increases oil and nitrogen capacity, which allows the shock to dissipate heat faster and maintain performance during hard use.

Will these shocks fit with aftermarket shock mounts?
No, these shocks are specifically designed to work only with Factory OEM Mounts and are not compatible with kits that modify stock mounts.

What lift height are these shocks compatible with?
These shocks are configured for vehicles equipped with 4 to 6 inches of rear lift.
