Product Description

The KYB 344385 is a nitrogen gas-charged, twin-tube Excel-G rear shock absorber engineered to restore the original ride control and handling of a wide range of GMT800-platform GM trucks and legacy Ram 1500 platforms. Covering Chevrolet and GMC Silverado/Sierra models from 1999 through 2010 (including all Classic sub-models), Dodge Ram 1500 from 2002-2010, Ram 1500 from 2011-2018, and Ram 1500 Classic through 2023, the 344385 is one of the most broadly applicable rear shocks in the GM/Ram truck segment. Built on the same KYB OEM assembly lines with vehicle-specific damping valves, it delivers the precise ride characteristics the manufacturer engineered - not an altered or performance-biased tune.

The triple chrome-plated piston rod and multi-lip synthetic seal system minimize internal wear and prevent contamination ingress, extending the service life of the unit well beyond budget alternatives. The included dust boot protects the shaft from road debris. With an E2 mount on both ends and a 10.43 in. stroke, the 344385 is a direct-fit replacement requiring no modifications. Sold individually - replace in pairs for balanced rear suspension performance. Backed by KYB's limited lifetime warranty.
