Rancho RS9000XL 5-6″ Rear Lift Shocks for 1988-1999 Chevy K1500 4WD

Part Number: RS999060

Summary: The Rancho RS9000XL series is the global benchmark for adjustable damping control, specifically engineered for lifted Chevy and GMC platforms. Featuring a signature 9-position manual adjustment knob, these shocks allow drivers to instantly transition from a plush street ride to a firm, controlled setting for heavy towing or off-road excursions. Designed to accommodate 5-6 inches of rear lift, they provide the necessary travel and damping force to maintain stability in high-clearance applications.

Features

• 9-Position Tuning: A manual adjustment knob provides 400% change in damping force to ensure total control over ride quality and firmness.
• Large Shock Body: A 2.75-inch liquid metallic finish body provides increased fluid capacity to ensure cooler operation during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road surface changes to ensure consistent tire-to-ground contact.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a 9-position knob at the base of the shock body. Simply turn the dial to your desired setting; lower numbers for a softer ride and higher numbers for increased firmness.

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured for vehicles that already have 5 to 6 inches of rear lift height installed.

What is the benefit of the large 2.75-inch body?
The oversized body allows for a larger oil reservoir, which helps dissipate heat more efficiently than standard shocks, preventing damping fade during aggressive use.
