Rancho RS90000XL 4″ Front Lift Shocks for 1992-1999 GMC Suburban 1500 2WD

Part Number: RS999128

Summary: The Rancho RS9000XL series provides the ultimate in ride control versatility for your lifted GMC Suburban. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile from soft for daily commuting to firm for heavy towing or off-road stability. Engineered to accommodate a 4-inch lift, these shocks solve the problem of “one size fits all” valving by putting the final ride quality in the driver’s hands.

Features

• 9-Position Tuning: A manual adjustment knob provides 9 levels of damping control to ensure the perfect ride quality for any load or terrain.
• 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 optimization provides a barrier between the oil and gas to ensure consistent performance by preventing aeration.
• Heavy-Duty Piston: A 18mm nitro-carburized rod provides structural rigidity and scuff resistance to ensure long-term seal integrity.

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; No tools are required for adjustment.

Will these shocks lift my GMC Suburban?
No, these shocks do not create lift. They are specifically configured for vehicles that already have a 4-inch lift kit installed to ensure proper travel and geometry.

What is the benefit of the larger 2.75-inch body?
The increased surface area and oil volume allow the shock to dissipate heat more efficiently, preventing “shock fade” during repetitive cycles or heavy hauling.
