2011-2025 GM HD Rear Performance Series 2.5 Shock Absorber 1.5-2.5" Lift (FOX98724011)

For trucks and SUVs with coilovers at all four corners, these bolt-on, Performance Series 2.5 IFP shocks provide a comfortable on-road ride and predictable off-road handling. Their 2.5" diameter aluminum bodies dissipate heat faster than steel, and the Internal Floating Piston (IFP) 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.
