Rancho RS9000XL 1.5″ Rear Lift Shocks for 1967-1986 GMC C1500 2WD

Part Number: RS999118

Summary: The Rancho RS9000XL series is the industry benchmark for adjustable damping control, specifically engineered for the GMC C1500 2WD with rear leaf springs. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting for heavy towing or hauling. Designed to accommodate a 1.5-inch rear lift, they provide the necessary travel and damping capacity to maintain stability and comfort across various load conditions.

Features

• MyRide Tuning System: A 9-position manual adjustment knob provides custom damping control to ensure optimal ride quality for both daily commuting and heavy-duty towing.
• Large Diameter Body: A 2.75-inch tri-tube body provides increased fluid capacity to ensure cooler operating temperatures during high-demand use.
• Nitrogen Gas Pressurization: High-pressure gas charge provides a consistent response and minimizes aeration to ensure fade-free performance.
• Heavy-Duty Rod: A 18mm nitro-carburized piston rod provides exceptional structural rigidity and corrosion resistance to ensure long-term durability in harsh environments.

Frequently Asked Questions

What does the 9-position knob actually change?
The knob adjusts the internal bypass valving, allowing you to increase or decrease the resistance of the shock’s compression and rebound strokes to match your load or comfort preference.

Will these shocks lift my GMC C1500?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to operate on vehicles already equipped with a 1.5-inch rear lift.

Do I need tools to adjust the settings?
No, the MyRide adjustment knob is designed for manual operation, allowing you to change your ride profile in seconds without any specialized tools.
