Description

Smooth out rough roads and keep your truck planted on and off the pavement with the Rancho RS5000X Suspension Shock Absorber RS55370, a front-position damper built on Rancho's exclusive Cross Tuned technology. It drops in as a direct-fit replacement for the listed applications, including the 2002-2006 Chevrolet Avalanche 2500, 1999-2004 Chevrolet Silverado 2500, 2001-2010 Chevrolet Silverado 2500 HD, 2000-2013 Chevrolet Suburban 2500, 2001-2010 GMC Sierra 2500 HD, 2000-2013 GMC Yukon XL 2500, and 2003-2009 Hummer H2 — see the Buyer's Guide tab for the full list and engine details.

Cross Tuned technology: an exclusive rebound valving system and advanced compression phase designed to improve overall handling and performance on and off road.
Strong and durable: 16 mm nitro-carburized piston rod that resists scuffs and corrosion, double-welded loops at stress areas, a 35 mm sintered iron piston, and a polyvinyl protective boot.
Handles temperature swings: large twin-tube body filled with all-weather fluid for cooler operation, rated to withstand internal temperatures of -40 to 248°F.
Reduces fade: nitrogen gas pressurized to 150 PSI to minimize air-to-oil mixing, plus a polyurethane rebound bumper and rubber bushings to help absorb ride harshness.

Backed by Rancho's Limited Lifetime Warranty.
