Rancho RS9000XL 1.5″ Front Lift Shocks for 1987-1989 GMC R2500 2WD

Part Number: RS999120

Summary: The Rancho RS9000XL series provides 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 to accommodate a 1.5-inch front lift, they provide the necessary travel and damping force to maintain stability on classic GMC R2500 platforms.


Features

  • 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride for street, towing, or off-road use.
  • Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and consistent damping under heavy loads.
  • Nitrogen Gas Charged: High-pressure gas charging provides a reduction in aeration and foaming to ensure immediate response during rapid suspension cycling.
  • Heavy-Duty Piston: A 18mm nitro-carburized rod provides exceptional structural rigidity to ensure long-term durability in demanding environments.

  • Performance Benefit: Drivers gain the ability to eliminate “mushy” handling when loaded and harsh ride quality when empty by simply turning a dial.

Each shock features an external 9-position knob at the base. Turning the knob allows you to manually cycle through different valving profiles from soft to firm.
