Fits select 1988-2000 Chevrolet and GMC K1500, K2500 Suburban, Blazer, Tahoe, Yukon, and Sierra models.

The Rancho RS9000XL adjustable shock absorber provides premium control for drivers who demand versatility. Featuring a nine-position manual adjustment knob, these shocks allow you to customize damping levels for different environments—from smooth highway cruising to heavy towing or aggressive off-road use. The large 2.38-inch tri-tube body is filled with all-weather fluid to ensure consistent performance even as internal temperatures reach up to 248°F.

Built for durability on hardworking vehicles, this shock features a nitrogen gas charge to minimize oil foaming and fade. The assembly includes a low-friction, self-lubricating seal to protect against contaminants and a liquid metallic finish with a 2K clear coat for maximum chip resistance. Polyurethane bushings and a graphite-filled fluon-banded piston are utilized to reduce ride harshness and improve responsiveness to changing terrain.
