Overview
The Rancho RS55827 is a front RS5000X Series shock absorber for the 2004 through 2008 INFINITI QX56, the 2005 through 2015 Nissan Armada, and the 2005 through 2015 and 2017 through 2019 Nissan Titan.
It has a compressed length of 10.80 inches, an extended length of 14.63 inches and 3.83 inches of travel. The shock is gas charged, with progressive engagement valving, a tuned compression control valve and an enlarged 2-1/4-inch twin tube body. It uses a 16 mm nitro-carburized rod and a full-displaced 35 mm bore.
The valving was developed by Rancho’s engineers to improve on and off road handling and performance. It is a twin tube design.

Shock absorbers and body control
Large SUVs carry heavy loads and rely on their shocks to control body movement after bumps, during braking and when cornering. A shock that is losing damping lets the body keep moving after the road has changed, which feels floaty and can make braking less stable. Because the front and rear work together, a worn front shock changes how the whole vehicle responds.
When replacing a twin tube shock, keep the rubber bushings and mounting hardware in good condition, since a cracked bushing can make a new shock knock or feel loose. Check the shock body for oil seepage and the rod for pitting or scoring, which can damage the seal. Keep the boot in place once installed so road grit stays off the rod.
- Look for oil seepage on the body
- Check rubber bushings for cracks
- Inspect the rod for pitting or scoring
- Replace shocks in pairs for matched control
