Rancho RS9000XL 0″ Rear Lift Shocks for 1953-1975 Jeep M38A1 4WD

Part Number: RS999119

Summary: The Rancho RS9000XL series provides industry-leading adjustability for classic Jeep and utility applications. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly toggle between a soft street ride and a firm setting for heavy-duty use or towing. Engineered to handle the specific demands of the Jeep M38A1 and FJ-8A platforms, these shocks provide a custom-tailored suspension response that OE components cannot match.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride quality for any terrain or load requirement.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and consistent damping during heavy use.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road irregularities to ensure tire-to-road contact is maintained.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.
