Part Number: 980-24-956

Summary: The FOX 2.0 Performance Series Reservoir shocks deliver race-dominating performance in a hassle-free bolt-on package for the GMC Sierra 2500HD. Featuring an external reservoir system, these shocks are engineered to dissipate heat faster than conventional designs, ensuring consistent damping during demanding use. The metal-impacted aluminum body and Internal Floating Piston (IFP) technology provide a predictable ride quality capable of handling the roughest road conditions while maintaining high-pressure nitrogen gas separation.

Features

• External Reservoir System: High-capacity external reservoir dissipates heat fast to provide fade-resistant performance during sustained operation.
• Aluminum Body: Metal-impacted aluminum construction dissipates heat faster than steel to ensure consistent damping temperatures.
• Internal Floating Piston (IFP): Internal gas/oil separation provides a predictable ride quality to ensure performance in rough road conditions.
• Nitrile Bushings: Durable nitrile material allows for increased articulation to ensure maximum suspension movement.
• Redundant Sealing System: Multi-stage sealing provides long-lasting performance to ensure durability in harsh environments.

Technical Specifications

Fitment

• 2001-2010 GMC Sierra 2500HD

Why Choose This Product?

• Engineering Advantage: The external reservoir system significantly increases oil and nitrogen capacity, which combined with the aluminum body, manages heat far more effectively than standard twin-tube or steel shocks.
• Performance Benefit: Drivers experience a predictable, fade-free ride that is specifically tuned for the GMC Sierra 2500HD application, maintaining control even when the suspension is worked hard over rough terrain.

Frequently Asked Questions

What is the benefit of the external reservoir on these shocks?
The external reservoir system is designed to dissipate heat fast, which prevents shock fade and maintains consistent performance during aggressive driving or rough conditions.

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

Are these shocks serviceable?
Yes, according to the manufacturer, these Performance Series shocks are 100 percent serviceable and tunable for a longer lifespan.
