Rancho RS9000XL 2.5-4″ Rear Lift Shocks for 1969-1980 Chevy K10 4WD

Part Number: RS999112

Summary: The Rancho RS9000XL series delivers industry-leading versatility for classic Chevy K10 owners who demand performance across diverse driving conditions. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile from soft street cruising to firm off-road control or heavy towing support. Engineered for vehicles with 2.5 to 4 inches of rear lift, they provide the necessary travel and heat dissipation required for larger tire configurations and rugged 4WD applications.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure customized ride control for street, trail, or towing.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and reduced fade during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a consistent response by minimizing aeration to ensure predictable handling in rapid-cycling environments.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure seal longevity against mud and debris.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
Simply turn the 9-position knob located at the base of the shock body to your desired setting; 1 is the softest and 9 is the firmest.

Will these shocks lift my Chevy K10?
No, these shocks do not create lift. They are specifically configured for vehicles that already have 2.5″ to 4″ of rear lift installed.

Can I use these on a stock height truck?
These are extended-length shocks. Using them on a stock height vehicle may cause the shock to bottom out prematurely, potentially damaging the internal valving.
