Summary: The FOX 2.0 Performance Series Reservoir shocks provide race-dominating performance for the GMC Sierra 2500HD in a convenient bolt-on package. Utilizing an External Reservoir System and a metal-impacted aluminum body, these shocks are engineered to dissipate heat faster than conventional steel components. The Internal Floating Piston (IFP) design ensures consistent, predictable ride quality by separating shock oil from the high-pressure nitrogen gas chamber, making them ideal for handling the roughest road conditions while maintaining durability.

Features

• External Reservoir System: High-capacity external reservoir provides increased oil volume to ensure faster heat dissipation during sustained operation.
• Internal Floating Piston (IFP): Internal Floating Piston (IFP) technology separates shock oil from the high-pressure nitrogen gas chamber to provide predictable ride quality across rough terrain.
• Aluminum Body: Metal-impacted aluminum construction provides faster heat dissipation than steel to ensure consistent performance.
• Nitrile Bushings: Durable nitrile material provides increased articulation to ensure improved suspension movement.
• Redundant Sealing System: Multi-layer seal configuration provides protection against contaminants to ensure long-lasting performance.

Frequently Asked Questions

Are these shocks compatible with all lift kits?
No, these shocks only work with Factory OEM Mounts. They are not compatible with lift kits that modify stock mounts, such as those from Rough Country.

What is the benefit of the External Reservoir System?
The External Reservoir System allows the shocks to dissipate heat faster, which maintains performance stability during off-road use.

What does the Internal Floating Piston (IFP) do?
The IFP separates the shock oil from the high-pressure nitrogen gas, which eliminates oil aeration and provides a predictable ride quality.
