Rancho Suspension RS994048 RS9000XL 9-Position Adjustable Shock Absorber

The Rancho RS9000XL RS994048 suspension shock absorber delivers premium control and performance for trucks, SUVs, and Jeeps. Recognized as the first nine-position manually adjustable ride control series in the off-road market, this shock allows drivers to customize damping and firmness with a simple turn of the adjustment knob—ideal for on-road driving, off-road adventures, towing, and hauling.

Key Features:

• Nine-position adjustable knob provides unprecedented control over ride firmness and damping characteristics
• Nitrogen gas pressurized to 120 PSI to minimize air-to-oil mixture and reduce damping fade and foaming
• Application-specific 18mm nitro-carburized piston rod resists scuffs and corrosion
• 1.25-inch sintered iron piston enhances structural integrity and performance
• Large tri-tube body design (up to 2.75 inches) increases fluid capacity for cooler, more consistent operation
• Polyurethane rebound bumper and bushings absorb ride harshness for smoother performance
• Graphite-filled fluon-banded piston enhances responsiveness to changing road conditions
• Low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression
• Double-welded loops at stress areas for enhanced durability
• Premium liquid metallic finish and polyvinyl protective boot ensure long-lasting performance
• All-weather fluid allows operation in temperatures from -40°F to 248°F

The RS9000XL series is engineered for stock or lifted vehicles and excels at counteracting the additional unsprung mass inherent in larger tire and wheel combinations. Whether you're navigating rough terrain, towing heavy loads, or cruising the highway, simply adjust the shock setting to match your driving conditions. Settings 1-3 provide a comfortable OE-style ride, 4-6 offer a slightly firmer feel, and 7-9 are optimized for towing and heavy loads. Backed by Rancho's Limited Lifetime Warranty.
