Part Number: RS999329 / RS999330

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the Jeep Wrangler JK through its globally recognized adjustable damping technology. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting optimized for heavy towing or aggressive off-road crawling. Engineered specifically for vehicles with a 4-inch lift, these shocks provide the necessary travel and damping control to manage the increased center of gravity of a lifted Jeep.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the vehicle is perfectly calibrated for street, trail, or hauling duties.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during extended off-road use.
• Nitrogen Gas Charged: High-pressure gas optimization provides consistent valving response to ensure reduced aeration and foaming in demanding conditions.
• Polyurethane Bushings: Heavy-duty mounting material provides enhanced durability and vibration isolation to ensure a quiet and controlled cabin environment.
