Add the latest in shock technology to your 2001-2019 GM 2500HD/3500HD with the Fox 980-24-958 2.0 Performance Series IFP Shock Absorber. These shock absorbers are designed to transform your truck's performance, utilizing Fox's race-proven damping control to provide a comfortable on-road ride and predictable off-road handling, even in the toughest conditions. The precision metal impact aluminum body enhances cooling capacity and resists rust, ensuring long-lasting durability. Inside, you'll find race-proven performance valving technology. The Internal Floating Piston (IFP) mono-tube design separates the shock oil from the high-pressure nitrogen-charged gas chamber, eliminating oil aeration and allowing maximum performance through factory-tuned precision valving. The race-developed high-flow damping piston, paired with application-specific valving, delivers a predictable ride quality capable of handling the roughest terrains.
Features:
- Body: 2.0" Metal impacted 6061-T6 aluminum resists rust over time
- Body Plating: Clear anodized for a durable finish
- Internal Reservoir: Internal IFP mono-tube reservoir design separates shock oil from high-pressure nitrogen
- Components: Black-anodized, CNC-machined 6061-T6 billet aluminum
- Shaft: 5/8" hard chrome plated heat-treated alloy steel
- Piston: Race-developed high-flow piston design
- Valving: Application-specific valving to maximize performance
- Seals: Redundant sealing pack system including main seal, wiper seal, scraper seal
- Oil: JM92 Advanced Suspension Fluid for improved performance at variable temperatures
- Bushings: Quiet nitrile rubber allows for increased suspension articulation
- Mounting: Direct replacement for stock and aftermarket lift kits
Specifications:
- Extended Length: 33.850"
- Collapsed Length: 20.750"
- Top Mount: ES6
- Bottom Mount: ES6
- Applications: 2001-2019 GM 2500HD/3500HD - Rear, Lifted 7"-10"*
Note: Lift height is suggested by Fox. Due to various aftermarket suspension systems, it is recommended to take measurements for proper application. Images may not depict the exact product. Shock absorbers are sold individually.
