Rancho RS9000XL 0-2″ Rear Lift Shocks for 1981-1986 Chevy K10 4WD

Part Number: RS999118

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the Chevy K10 4WD, featuring a globally recognized 9-position manual adjustment system. This Tier 2 adjustable shock allows drivers to instantly transition from a soft street ride to a firm setting for heavy towing or aggressive off-road use. Engineered for vehicles with 0-2 inches of rear lift, these shocks provide the custom tuning necessary to manage varying loads and terrain conditions without compromising ride quality.

Features

• 9-Position Tuning: A manual adjustment knob provides nine unique levels of damping resistance to ensure the perfect ride for street, towing, or off-road applications.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy cycles.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road inputs to ensure consistent performance and reduced aeration.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.
