Part Number: RS999056

Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty applications. Featuring a 9-position manual adjustment knob, these shocks allow owners to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road stability. Engineered specifically for the Ram 3500 4WD with a 4-inch rear lift, these shocks provide the extra travel and damping control required for high-clearance suspension systems.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the vehicle is perfectly tuned for daily driving, towing, or hauling.
• Nitrogen Gas Pressurization: High-pressure gas charging provides rapid response and minimizes aeration to ensure consistent performance under heavy loads.
• Nitro-Carburized Piston Rod: A 18mm heavy-duty rod diameter provides exceptional structural integrity to ensure long-term durability in harsh environments.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure lower operating temperatures during demanding use.
