Fox Perf Series 2.0 Smooth Body Reservoir 1.5-2.5 inches Front Lift Shocks for 2020-2023 GMC Sierra 2500/3500 2WD/4WD

Part Number: 985-24-244

Summary: The FOX Performance Series 2.0 Reservoir smooth body shocks are engineered for the 2020-2023 GMC Sierra 2500/3500 to provide a significant upgrade in damping control. By utilizing an External Reservoir, these shocks increase oil and nitrogen capacity to manage heat more effectively than conventional designs. This setup is specifically tuned to provide a comfortable on-road ride while maintaining predictable handling in tough off-road conditions.

Features

• External Reservoir: 2.0 inches Smooth bore 6061-T6 Aluminum hard anodized reservoir provides increased oil and nitrogen capacity to ensure consistent performance and a race-inspired aesthetic.
• Aluminum Body: 2.0 inches Impact extruded 6061-T6 aluminum construction provides superior heat dissipation to ensure the shock resists rust and maintains thermal stability.
• Internal Floating Piston (IFP): Mono-tube design separates shock oil from the high-pressure nitrogen chamber to provide consistent damping by eliminating oil aeration.
• High-Flow Piston: Race-developed high-flow piston design provides application-specific valving to ensure a predictable ride quality capable of handling rough road conditions.
• Redundant Sealing Pack: Main seal, wiper seal, and scraper seal system provides maximum protection to ensure long-term durability in harsh environments.

Technical Specifications

Fitment

• 2020-2023 GMC Sierra 2500 2WD/4WD
• 2020-2023 GMC Sierra 3500 2WD/4WD
• Note: Requires Upper Control Arm.

What’s Included

• Includes 2 Shocks

Why Choose This Product?

• Engineering Advantage: The use of an external reservoir combined with a clear-anodized aluminum body allows these shocks to dissipate heat significantly faster than steel-bodied shocks, preventing performance fade.
• Performance Benefit: Drivers experience a precise, predictable ride quality that balances daily street comfort with the durability required for sustained off-road use.

Frequently Asked Questions

What is the benefit of the external reservoir on these FOX shocks?
The external reservoir increases the total oil and nitrogen capacity of the shock, which helps dissipate heat faster and delivers consistent damping during aggressive use.

Are these shocks compatible with a stock GMC Sierra 2500/3500?
These shocks are designed for vehicles with 1.5-2.5 inches of front lift and specifically require the use of an aftermarket Upper Control Arm for proper fitment.

How does the Internal Floating Piston (IFP) improve ride quality?
The IFP separates the nitrogen gas from the shock oil, which prevents the oil from foaming (aeration), ensuring the valving remains consistent and predictable.
