The Rancho RS9000®XL Rear Shock Absorber delivers premium ride control for stock-height Super Duty trucks that demand versatility for daily driving, towing, hauling, and light off-road use. Featuring Rancho’s proven nine-position adjustable damping, this shock allows you to fine-tune ride firmness to match changing loads, road conditions, and driving demands.

Built for hard-working trucks, the RS9000®XL utilizes a gas-pressurized tri-tube design to reduce shock fade and maintain consistent performance under heat and heavy use. An 18mm nitro-carburized piston rod provides excellent resistance to corrosion and wear, while the oversized 2.75" shock body improves cooling and long-term durability.

Designed to improve control and stability on factory-height suspension systems, this rear shock helps manage body motion and enhances ride comfort whether you’re on the highway, at the jobsite, or towing heavy loads.
