Rancho RS5000X Rear Shock Absorber for 1984-1998 Toyota 4Runner, Land Cruiser, Pickup & Tacoma - RS55144

Fits select 1984-1998 Toyota 4Runner, Land Cruiser, Pickup, and Tacoma models.

The Rancho RS5000X Rear Shock Absorber (RS55144) is engineered for versatile performance, bridging the gap between daily street driving and rugged off-road use. Utilizing Rancho's exclusive Cross Tuned technology, this twin-tube shock features a unique rebound valving system and an advanced compression phase that improves handling and reduces impact harshness across various terrains.

Built for durability, the RS5000X is constructed with a large twin-tube body and a 16mm nitro-carburized piston rod to resist scuffs and corrosion. The internal 35mm sintered iron piston provides structural integrity, while the nitrogen gas charge, pressurized to 150 PSI, minimizes aeration and foaming to prevent damping fade during intensive use. A self-lubricating seal and fluon-banded piston ensure smooth operation and quick response to changing road conditions.
