Rancho Suspension Shock Absorber P/N:RS55115
Soak up rough terrain and keep every wheel planted with the Rancho RS5000X shock absorber (MPN RS55289), a FRONT-position damper built around Rancho's exclusive Cross Tuned technology. It's a direct-fit replacement for the 2001-2010 Chevrolet Silverado 2500 HD, 2007 Chevrolet Silverado 2500 HD Classic, 2001-2010 GMC Sierra 2500 HD, 2007 GMC Sierra 2500 HD Classic, and 2003-2009 Hummer H2 — see the "Vehicles it fits" section for engine-level detail.
Nitrogen gas pressurized to 150 PSI helps minimize air-to-oil mixing to reduce foaming and damping fade, while a polyurethane rebound bumper, rubber bushings, and a fluon-banded piston help absorb harshness. Backed by Rancho's Limited Lifetime Warranty.

Will this Rancho shock absorber fit my truck?
It's a direct-fit FRONT shock for the 2001-2010 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD, the 2007 Classic variants of both, and the 2003-2009 Hummer H2. Check the "Vehicles it fits" section to confirm.
What is Cross Tuned technology?
It's Rancho's exclusive rebound valving system paired with an advanced compression phase, designed to improve overall handling and performance on and off road.
Is this shock gas-charged?
Yes. It's a nitrogen gas-pressurized twin-tube design at 150 PSI, which helps minimize air-to-oil mixing to reduce foaming and damping fade.
What temperature range can it handle?
The large twin-tube body is filled with all-weather fluid rated to withstand internal temperatures of -40 to 248°F for cooler operation.
Should I replace shocks in pairs?
This listing is for one shock. Replacing both sides on an axle together is recommended for balanced, even ride control.
