Rancho 04-12 Chevrolet Colorado Rear RS9000XL Shock (Available to order MARCH 2026)

The Rancho RS9000XL shock absorber uses a tri-tube body, measuring up to 2.38 inches, which helps it handle extreme temperature changes. This design, filled with all-weather fluid, allows for cooler operation and better vehicle control, even in temperatures from -40 to 248°F. It's built to last with a low-friction seal that retains gas and oil for quicker rebound and smoother compression, while a premium liquid metallic finish and protective boot add durability.

What really sets this shock apart is its nine levels of adjustable damping. A simple knob lets you dial in the firmness you need, whether you're cruising on the highway or tackling rough terrain off-road. This adjustability helps reduce fade by keeping the nitrogen gas pressurized, minimizing air-to-oil mixing and preventing foaming. It's a solid option for stock or lifted trucks, SUVs, and Jeeps that tow, haul, or venture off the beaten path, offering a bold new look with a chip-resistant paint finish.
