Rancho RS5000X 0″ Rear Lift Shocks for 1953-1975 Jeep M38A1 4WD

Part Number: RS55119

Summary: The Rancho RS5000X series utilizes an innovative CrossTune Technology to provide a significant upgrade in ride quality for the Jeep M38A1 and FJ-8A. By utilizing a unique valving system and a large 2.25-inch reserve tube, these shocks are designed to handle the rigors of off-road terrain while maintaining smooth street manners. This twin-tube gas pressurized design is specifically engineered to reduce internal fluid temperature and prevent aeration, ensuring consistent damping performance during extended use.

Features

• CrossTune Technology: A unique base valve system provides a progressive engagement throughout the piston stroke to ensure a balanced ride on any terrain.
• Twin-Tube Design: A 2.25-inch reserve tube provides increased fluid capacity to ensure lower internal operating temperatures and reduced fade.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides enhanced structural rigidity to ensure long-term durability against debris and corrosion.
• Polyurethane Bushings: High-density mounting material provides superior vibration dampening to ensure a quiet and controlled cabin environment.
