Add the latest in shock technology to your 2001-2019 GM 2500HD/3500HD with the Fox 980-24-664 2.0 Performance Series IFP Shock Absorber. The 2.0 Performance Series Shock Absorbers will 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 increases cooling capacity and is rust-resistant. Inside, you'll find race-proven performance valving technology. The Fox Internal Floating Piston (IFP) mono-tube design separates the shock oil from the high-pressure, nitrogen-charged gas chamber. The IFP eliminates oil aeration, allowing maximum performance from the factory-tuned precision valving. The race-developed high-flow damping piston, matched with application-specific valving, provides the 2.0 Performance Series IFP shock with a predictable ride quality capable of handling the roughest road conditions.
