Rancho RS5000X Rear Shock for Titan

The Rancho RS5000X RS55394 is a rear suspension shock absorber built for Nissan Titan and Titan XD applications that need controlled damping on pavement and improved stability off-road. Its valving and compression-focused design help deliver more consistent handling over rough roads, towing loads, and uneven terrain.

RS5000X Series Overview

Rancho RS5000X shocks are tuned for drivers who want firmer control without giving up everyday ride quality. This line uses an exclusive valving system and advanced compression functionality to improve response at the rear axle, making it a practical upgrade for Nissan Titan and Nissan Titan XD trucks used for commuting, hauling, and trail driving.

Key Features

  • Part number RS55394 rear suspension shock absorber
  • Extended length: 24.25 in.; compressed length: 15.06 in.
  • Travel length: 9.19 in. for rear suspension movement
  • Dust shield included for added protection
  • Extended bumper stop included
  • Loop bushing and sleeve mounts: LS47 upper, LS44 lower
  • Reserve tube diameter: 2.251 in.

Detailed Description

Built for the rear of select Nissan Titan and Titan XD trucks, the Rancho RS5000X RS55394 uses a valving setup aimed at improving control during compression and rebound. That helps the rear suspension stay composed over bumps, washboard roads, and load changes. The loop bushing and sleeve mounting design supports a direct-fit replacement on listed applications, while the included dust shield adds protection in exposed underbody conditions. This shock absorber is a strong match for drivers looking to restore rear damping performance on a Nissan Titan or Nissan Titan XD with the correct factory configuration.

This part cross-references KYB 345042 for the same application.

What It Helps Address

  • Excessive rear-end bounce after bumps
  • Reduced stability on rough pavement or gravel roads
  • Weak damping from worn rear shocks
  • Uncontrolled rear suspension movement under load
  • Harsh or inconsistent rear ride response

Installation Notes and Fitment

Fits 2016-2024 Nissan TITAN XD, rear. Fits 2004-2015 Nissan TITAN, rear, without Off Road Package and with Rear Raised Height 0 in.

  • Verify upper and lower mount codes LS47 and LS44 before installation.
  • Confirm compressed and extended lengths match the vehicle’s rear suspension travel.
  • Inspect bushings, sleeves, and mounting points for wear before replacing the shock.
  • Use the listed fitment notes for Titan models with rear raised height 0 in. and without the Off Road Package.

Quality Assurance

Rancho RS5000X shocks are engineered around a dedicated valving system and compression control strategy for consistent rear suspension performance. RS55394 is built to the listed dimensions and mounting specifications for the confirmed Nissan Titan and Titan XD applications.
