Rancho RS9000XL 0″ Rear Lift Shocks for 1988-1999 Chevy K1500 4WD

Part Number: RS999190

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the Chevy K1500 and GMC Yukon, featuring a globally recognized 9-position manual adjustment knob. This Tier 2 adjustable technology allows drivers to instantly transition from a soft, compliant street ride to a firm, controlled setting for heavy towing or off-road excursions. Engineered to maintain factory ride height, these shocks provide a custom-tuned damping solution that adapts to your specific cargo and terrain requirements.

Features

• 9-Position Tuning Knob: Manual adjustment technology provides nine distinct levels of damping force to ensure optimal ride control across various payloads and terrains.
• Nitrogen Gas Pressurized: High-pressure gas charge provides a consistent response by minimizing oil foaming to ensure fade-free performance during spirited driving.
• Large Diameter Body: Increased fluid capacity provides superior heat dissipation to ensure the shock maintains consistent valving under heavy-duty use.
• Protective Boot: Durable polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.

• Performance Benefit: Eliminates the compromise between comfort and capability, giving the driver total control over vehicle sway and rebound during towing.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a 9-position knob located at the base of the shock body; simply turn the dial to your preferred setting—1 for softest and 9 for firmest.

Will these shocks lift my Chevy K1500?
No, these shocks do not create lift. They are specifically configured for vehicles with 0 inches of rear lift height to maintain factory geometry.

What is the benefit of the nitrogen gas charging?
The gas charge puts the internal hydraulic fluid under pressure, which prevents the air bubbles (aeration) that typically cause shocks to lose their damping effectiveness during rough driving.
