Rancho Suspension Shock Absorber P/N:RS55378
Smooth out the ride and regain control with the Rancho RS5000X shock absorber (RS55297), a rear-position damper built around Rancho's exclusive Cross Tuned technology. It installs as a direct-fit replacement for the listed trucks and SUVs — including the 1999-2018 Chevrolet Silverado 1500, 1999-2018 GMC Sierra 1500, 2002-2008 Dodge Ram 1500, 2002-2006 Chevrolet Avalanche 2500, and 2003-2009 Hummer H2. See the "Vehicles it fits" section for the full list of applications.
A polyurethane rebound bumper, rubber bushings, and a fluon-banded piston help absorb harshness, while the Compression Control Valve and low-friction self-lubricating seal support consistent motion control. If worn rear shocks are behind excessive bounce or poor ride control, this unit replaces them. Sold individually; replacing both sides as a pair is recommended for balanced ride quality. Backed by Rancho's Limited Lifetime Warranty.
