Rancho RS994259 RS9000XL 9-Position Adjustable Shock Absorber

The Rancho RS9000XL RS994259 is a premium 9-position manually adjustable shock absorber engineered for trucks, SUVs, and Jeeps that demand performance both on and off the road. Globally recognized as the first nine-position manually adjustable ride control series in the off-road market, the RS9000XL series delivers customizable damping and firmness at the turn of a knob.

Key Features:

• 9-Position Adjustment Knob: Dial in your preferred ride from soft to firm — settings 1–3 mimic OE ride quality, 4–6 provide a slightly firmer feel, and 7–9 are optimized for towing and heavy loads, delivering up to a 400% change in damping control from level 1 to level 9
• Nitrogen Gas Charged: Pressurized to minimize air-to-oil mixture, reducing damping performance fade and foaming under demanding conditions
• Oversized 2.75-Inch Tri-Tube Body: Increases fluid capacity for cooler, more consistent operation even under the most extreme use
• Heavy-Duty 18mm Nitro-Carburized Piston Rod: Delivers enhanced scuffing resistance and corrosion protection for long-term durability
• Graphite-Filled Fluon-Banded Piston: Paired with a 1-1/4-inch sintered iron piston for increased strength, structural integrity, and smooth operation
• Polyurethane Rebound Bumpers and Bushings: Absorb ride harshness and improve responsiveness to changing road and trail conditions
• Low-Friction Self-Lubricating Seal: Retains gas and oil for quicker rebound and smoother compression throughout the shock's service life
• Protective Polyvinyl Boot: Shields the shock rod and oil seal from debris and the elements for extended durability
• Premium Liquid Metallic Finish: Long-lasting coating engineered to withstand harsh environments

Ideal for stock or lifted trucks and SUVs used for towing, hauling, or off-road driving, the RS9000XL counteracts the additional unsprung mass of larger tire and wheel combinations while maintaining consistent tire-to-road contact for confident steering, handling, and braking. Installation is rod-up, body-down on most applications. Covered by a Limited Lifetime Warranty (standard applications).
