Rancho RS9000XL 0-1.5″ Rear Lift Shocks for 1981 Jeep Scrambler 4WD

Part Number: RS999113

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the 1981 Jeep Scrambler and FJ-9 chassis. Featuring a 9-position manual adjustment knob, these shocks allow owners to instantly tune damping levels to compensate for varying payloads or terrain transitions. Whether configured for daily street use or 1.5-inch rear lift applications, this nitrogen-gas charged system provides a custom-tailored ride quality that eliminates the compromises of fixed-valving shocks.

Features

• 9-Position Tuning: A globally recognized manual adjustment knob provides nine distinct levels of damping force to ensure precise control for towing, hauling, or off-road excursions.
• Large Shock Body: The 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charging: Pressurized gas implementation provides a reduction in aeration and foaming to ensure consistent damping response under rapid cycling.
• Heavy-Duty Nitro-Carburized Rod: The 18mm diameter piston rod provides superior structural rigidity and corrosion resistance to ensure long-term seal integrity.
