Rancho RS994055 RS9000XL 9-Position Adjustable Shock Absorber

The Rancho RS9000XL RS994055 is a premium, nine-position manually adjustable shock absorber engineered for trucks, SUVs, and Jeeps that demand versatility across on-road, off-road, towing, and hauling conditions. Globally recognized as the first nine-position manually adjustable ride control series in the off-road market, the RS9000XL delivers unprecedented damping control in a single shock.

Key Features:

• 9-Position Adjustable Damping: Easy-to-use knob provides nine distinct levels of firmness — positions 1–3 replicate an OE-style ride, 4–6 offer a slightly firmer feel, and 7–9 are optimized for towing and heavy loads, delivering up to a 400% change in control from softest to firmest
• Tri-Tube Body (up to 2.75 in.): Oversized triple-tube design increases fluid capacity, runs cooler under demand, and delivers consistent performance even in extreme conditions
• Nitrogen Gas Charged: Pressurized nitrogen minimizes air-to-oil mixture, reducing damping fade and fluid foaming during extended use
• Heavy-Duty 18mm Nitro-Carburized Rod: Provides increased scuffing resistance and corrosion protection for long service life
• 1-1/4 in. Sintered Iron Piston: Enhances overall strength and structural integrity for consistent performance
• Graphite-Filled Fluon-Banded Piston: Reduces friction and improves responsiveness to changing road surfaces for a smoother ride
• Polyurethane Bushings and Rebound Bumper: Absorbs ride harshness and boosts overall durability and performance
• Protective Boot & Liquid Metallic Finish: Polyvinyl boot shields the shock rod and oil seal; premium metallic finish ensures long-term corrosion resistance
• Sold Individually

The RS9000XL series is ideal for stock or lifted trucks, SUVs, and Jeeps used for towing, hauling, or tackling rugged terrain. Engineered and manufactured in the U.S., each unit is backed by a Limited Lifetime Warranty (standard units) or a 90-Day Limited Warranty (extended length and coil-over applications).
