The Rancho RS994048 RS9000XL suspension shock absorber is designed to deliver controlled, adaptable performance for trucks, SUVs, and Jeeps used on pavement, trails, and demanding work sites. Its nine-position adjustment knob lets you select the damping level that best matches changing loads, road conditions, towing demands, and off-road driving preferences. This adjustable design provides a practical balance between ride comfort and responsive handling.

The shock absorber uses an application-specific tri-tube body, all-weather fluid, and nitrogen gas pressurization to help maintain consistent operation across temperatures from -40 to 248°F. A low-friction, self-lubricating seal helps retain oil and gas for quicker rebound and smoother compression, while the graphite-filled fluon-banded piston, polyurethane rebound bumper, and polyurethane bushings help reduce harshness. Integrated bottom mounts enhance strength, and the dual-component 2K paint finish improves resistance to chips and wear. A protective polyvinyl boot helps shield the shaft and seal from road debris.
