Description

The Rancho RS999379 is a rear shock absorber designed for select GM Silverado and Sierra 2500HD/3500HD models. It features a 2.75-inch tri-tube body and 18mm nitro-carburized rod for durability. This shock offers nine levels of adjustable damping, controlled by an external knob, to fine-tune the ride for various conditions, from daily driving to towing and off-road performance.

Constructed with double-welded loops for strength and a painted silver finish with a protective boot, it's built for longevity. The shock is gas-charged to 120 PSI to help prevent fade. Its compressed length is 16.06 inches, and the extended length is 25.4 inches, with a travel length of 9.49 inches.
