FOX 2.0 Perf Res Adj 4-6 Lift Shocks 2011-2019 GMC Sierra 3500HD

Part Number: 980-26-966

Summary: The FOX 2.0 Performance Series Adjustable Reservoir shocks provide a high-performance suspension solution for the GMC Sierra 3500HD equipped with a 4-6 inch lift. These shocks feature a heat-reducing metal impacted 6061-T6 aluminum body and an external reservoir to increase oil and nitrogen capacity. The integrated CD Adjuster allows for manual tuning of the ride quality to handle varying road conditions. By utilizing application-specific valving and a race-developed high-flow piston, these shocks deliver predictable handling and improved heat dissipation over conventional steel body designs.

Features

• CD Adjuster: 8 clicks of compression adjustability provides user-tunable damping to ensure the ride can transition from very soft to very firm settings.
• External Reservoir: 2.0-inch smooth bore 6061-T6 aluminum construction provides increased oil and nitrogen capacity to ensure consistent performance and a race-inspired appearance.
• Aluminum Body: Metal impacted 6061-T6 aluminum provides superior heat dissipation to ensure the shock resists rust and maintains performance under high-temperature operation.
• High-Flow Piston: Race-developed design provides application-specific valving to ensure a predictable ride quality across rough terrain.
• Redundant Sealing Pack: Includes a main seal, wiper seal, and scraper seal provides a multi-layered barrier to ensure long-term seal integrity.

Frequently Asked Questions

How does the CD Adjuster work?
The CD Adjuster provides 8 clicks of compression adjustability, allowing you to manually tune the shock from a very soft to a very firm setting depending on your preference.

What are the benefits of the external reservoir?
The external reservoir increases the shock’s oil and nitrogen capacity, which improves heat management and provides a striking race-ready appearance.

Will these shocks fit a truck with factory magnetic suspension?
No, these shocks are explicitly noted as not fitting vehicles equipped with magnetic suspension systems.
