Rancho 99-06 Chevrolet Pickup / Silverado 1500 1/2 Ton Front RS9000XL Shock

Rancho is well-known for its suspension components, especially their adjustable shocks. This RS9000XL shock absorber, part number RS999263, is designed to fit a range of hardworking trucks like the 1999-2006 Chevrolet Silverado 1500 and 2007 Classic models, as well as comparable GMC Sierra trucks. It offers a significant upgrade in ride control and performance for daily driving, towing, or off-road adventures.

What sets the RS9000XL apart is its nine-position manual adjustability, allowing you to dial in the firmness to match your driving conditions. The shock features a large 2.75-inch tri-tube body that helps keep internal temperatures down, even in extreme weather from -40 to 248°F, which helps reduce damping fade. Inside, an 18mm nitro-carburized piston rod resists scuffs and corrosion, while a 1.25-inch sintered iron piston and a graphite-filled fluon-banded piston contribute to a smooth and responsive ride. A low-friction seal retains gas and oil, and double-welded loops add strength at stress points. The shock also includes a protective polyvinyl boot and a premium liquid metallic finish for a long service life.

This shock absorber is pressurized with nitrogen gas to 120 PSI, which helps prevent air from mixing with the oil and further reduces fade. It's an ideal choice for stock or lifted trucks and SUVs that are used for towing, hauling, or exploring off the beaten path. It comes with Rancho’s Limited Lifetime Warranty for peace of mind.
