Rancho 86-89 Toyota 4Runner Rear RS5000X Shock

The Rancho RS5000X is a gas-pressurized twin-tube shock absorber designed to enhance vehicle handling and performance both on and off-road. It features a 2-1/4-inch diameter shock body for increased fluid capacity, allowing it to run cooler and maintain control. The shock utilizes patented progressive engagement valving, which allows for early fluid flow to reduce harsh initial impacts and provides gradual fluid control. This design helps minimize a rough ride by allowing the piston to glide through initial travel with minimal force, while still engaging to maintain control and stability when needed.
