Rancho Suspension RS994190 RS9000XL 9-Position Adjustable Shock Absorber

The Rancho RS9000XL RS994190 shock absorber delivers premium control and performance with industry-leading nine-position adjustable damping technology. Recognized as the first nine-position manually adjustable shock series in the off-road market, this shock allows drivers to customize their ride quality for any condition—from smooth highway cruising to aggressive off-road terrain, towing, and heavy hauling.

Nine Levels of Adjustable Performance:

The easy-to-adjust knob located on the shock body provides nine distinct damping settings, offering up to 400% change in vehicle control from setting 1 to setting 9. Simply turn the knob to dial in your preferred ride: settings 1-3 deliver a comfortable OE-like ride, settings 4-6 provide a firmer feel for spirited driving, and settings 7-9 are optimized for towing and heavy loads.

Advanced Construction and Durability:

• Triple-tube design with oversized body (up to 2.75 inches diameter) increases fluid capacity for cooler operation and consistent performance
• Nitrogen gas charged to 120 PSI to minimize aeration and reduce damping fade and foaming
• Heavy-duty 18mm nitro-carburized piston rod resists scuffs and corrosion
• Graphite-filled fluon-banded piston enhances durability and responsiveness
• Polyurethane rebound bumper and bushings absorb ride harshness
• Low-friction, self-lubricating seal retains gas and oil for quicker rebound
• Protective polyvinyl boot shields the rod and oil seal
• Premium liquid metallic finish for long-lasting appearance
• Double-welded loops at stress areas ensure structural integrity

Ideal Applications:

Perfect for stock or lifted trucks, SUVs, and Jeeps used for daily driving, off-road adventures, towing, and hauling. The adjustable damping enhances ride characteristics by counteracting the additional unsprung mass from larger tire and wheel combinations.

Backed by Rancho's Limited Lifetime Warranty, the RS9000XL series represents decades of suspension engineering expertise from one of the industry's most trusted brands.
