2011-2025 GM HD 0-1" Rear HTO Shock (987-24-009)

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-inch 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.

• Body: 2.5-inch impact extruded, CNC machined 6061-T6 hard-anodized aluminum.
• Reservoir: Internal Floating Piston (IFP) monotube reservoir design.
• Shaft: 7/8" hard chrome plated heat-treated alloy steel.
• Valving: Application-specific valving with a race-developed high-flow piston.
• Mounting: Direct replacement for stock and aftermarket lift kits.
