Rancho RS994299 RS9000XL 9-Position Adjustable Suspension Shock Absorber

The Rancho RS9000XL RS994299 is a premium 9-position manually adjustable shock absorber engineered for trucks, SUVs, and Jeeps that demand versatile, high-performance suspension control 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 unmatched damping flexibility for towing, hauling, off-roading, and everyday driving.

Key Features:

• 9-Position Adjustable Damping: Easy-to-turn knob provides up to a 400% change in control from position 1 (softest, OE-like ride) to position 9 (firmest, ideal for towing and heavy loads)
• Nitrogen Gas Charged: Pressurized to 120 PSI to minimize air-to-oil mixture and reduce damping fade and foaming under demanding conditions
• Heavy-Duty 18mm Nitro-Carburized Piston Rod: Provides increased resistance to scuffing and corrosion for long-term durability
• Up to 2.75-Inch Tri-Tube Body: Increases fluid capacity for cooler operation and consistent performance, even under extreme conditions, with an internal temperature range of -40°F to 248°F
• 1.25-Inch Sintered Iron Piston: Delivers enhanced structural integrity and strength
• Graphite-Filled Fluon-Banded Piston: Works with polyurethane rebound bumpers and bushings to absorb ride harshness and improve responsiveness to changing road surfaces
• Low-Friction Self-Lubricating Seal: Retains gas and oil for quicker rebound and smoother compression throughout the shock's life
• Polyvinyl Protective Boot: Shields the shock rod and oil seal from dirt, debris, and the elements
• Premium Liquid Metallic Finish: Provides long-lasting corrosion resistance and a clean appearance
• Limited Lifetime Warranty: Backed by Rancho's confidence in materials and workmanship

Installation is straightforward — the RS9000XL is designed to be mounted rod-up, body-down. Once installed, simply dial in your preferred setting: positions 1–3 replicate a factory-like ride, positions 4–6 offer a slightly firmer feel, and positions 7–9 are optimized for towing and heavy payloads. The adjustable damping also helps counteract the additional unsprung mass from larger tire and wheel combinations, making this shock an excellent choice for lifted applications.
