Rancho RS9000XL 4″ Lift Shocks for 1988-2000 GMC C2500 2WD

Part Number: RS999128

Summary: The Rancho RS9000XL series delivers industry-leading versatility for drivers who demand total control over their ride quality. 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 hauling. Engineered specifically for the GMC C2500 2WD configured with a 4-inch lift, this set provides a custom-tailored solution to manage increased ride height while maintaining superior stability.


Features

  • MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the perfect balance between street comfort and heavy-duty control.
  • Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during demanding use.
  • Nitrogen Gas Charged: High-pressure gas integration provides a reduction in aeration and foaming to ensure consistent damping performance under load.
  • Heavy-Duty Fluon Banded Piston: A 1.25-inch sintered iron piston provides a consistent seal between the piston and pressure tube to ensure long-term durability.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
Each shock features a clearly numbered 9-position knob at the base of the body; simply turn the dial to your desired setting to increase or decrease damping resistance.

Will these shocks lift my GMC C2500 by 4 inches?
No, these shocks do not create lift. They are specifically valved and length-calibrated to work with a vehicle that already has a 4-inch suspension lift installed.

What is the benefit of the larger 2.75-inch shock body?
The increased surface area and fluid capacity allow the shock to dissipate heat more effectively than standard shocks, preventing performance fade during heavy hauling.
