Rancho RS5000X Rear Shock for Toyota

The Rancho RS5000X RS55144 is a suspension shock absorber built for rear applications on select Toyota trucks and SUVs. It uses Rancho’s RS5000X valving and advanced compression control to improve handling response on-road and stability off-road.

Compatible with Toyota Tacoma, Toyota Pickup, Toyota Land Cruiser, and Toyota 4Runner rear suspension setups listed below, this shock is a direct-fit option for vehicles with the specified raised-height and mounting requirements.

Key Features

  • Rancho RS5000X series shock absorber for rear suspension use
  • Exclusive valving system for more controlled damping response
  • Advanced compression functionality for improved ride control
  • Loop bushing upper and lower mounts with 3/4 in. bushing ID and 1.9/16 in. bushing OAL
  • Compressed length: 14.19 in.; extended length: 22.34 in.; travel length: 8.15 in.
  • No dust shield, compressed bumper stop, extended bumper stop, or extended hydraulic lockout included

Product Details

The Rancho RS55144 is part of the RS5000X product line, a shock family focused on controlled suspension movement for street and trail use. For Toyota Tacoma, Toyota Pickup, Toyota Land Cruiser, and Toyota 4Runner rear applications, the RS5000X tuning helps manage body motion and wheel control while matching the listed lift and mounting dimensions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Shock Helps Address

  • Excessive rear-end bounce after bumps or dips
  • Loose or unsettled rear suspension feel on rough roads
  • Reduced control when carrying load or driving off pavement
  • Worn rear shock performance on lifted Toyota applications
  • Inconsistent damping response from aging suspension components

Installation Notes

  • Fits 1995-1998 Toyota Tacoma, rear right, with Rancho Suspension System and rear raised height 1.0 in. to 1.5 in.
  • Fits 1986-1992 Toyota Pickup, rear, with Rancho Suspension System and rear raised height 3.0 in.
  • Fits 1988-1989 Toyota Land Cruiser, rear, with rear 0.75 in. diameter mount and rear raised height 0 in.
  • Fits 1986-1988 Toyota Pickup, rear, with rear raised height 0 in. to 1.0 in.

  • Fits 1984-1985 Toyota Pickup, rear, with rear raised height 0 to 2.0 in.

Verify rear mount style, lift height, and position before installation. The upper and lower loop bushing mounts should be matched to the vehicle’s existing hardware and suspension configuration.

Quality Assurance

Rancho RS5000X shocks are engineered around a dedicated valving strategy and compression tuning for consistent suspension control. The RS55144 is built to the published dimensions and fitment requirements for the listed Toyota applications.
