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

Part Number: RS999001

Summary: The Rancho RS9000XL series is the industry leader in adjustable damping, providing a custom-tailored ride for your Chevy K10. Featuring a 9-position manual tuning knob, these shocks allow you to transition from a soft street ride to firm control for heavy towing or off-road excursions in seconds. Engineered to accommodate 2.5 to 4 inches of lift, they provide the necessary travel and damping force to maintain stability and comfort on vintage 4WD platforms.

Features

9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride for any terrain or load requirement.
Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty use.
Nitrogen Gas Charged: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent damping performance.
Polyurethane Bushings: High-quality polyurethane material provides enhanced durability compared to rubber to ensure long-lasting pivot point integrity.

Why Choose This Product?

Engineering Advantage: Unlike “one-size-fits-all” shocks, the RS9000XL uses a globe-patented 9-position valve system that changes the bypass flow for true user-defined calibration.
Performance Benefit: Drivers gain the ability to stiffen the suspension for highway stability while towing and instantly soften it for improved articulation and comfort when hitting the trails.

Frequently Asked Questions

Do I need tools to adjust the stiffness?
No, the RS9000XL features an external manual knob that can be turned by hand to any of the nine settings.

Will these shocks lift my vehicle?
No, these shocks do not create lift; they are specifically configured for vehicles already equipped with a 2.5 to 4-inch lift kit.

What is the benefit of the large 2.75-inch body?
The larger body holds more hydraulic fluid, which helps dissipate heat faster and prevents “shock fade” during sustained off-road use.
