Rancho RS994305 RS9000XL 9-Position Adjustable Shock Absorber

The Rancho RS994305 is part of the RS9000XL series — globally recognized as the first nine-position manually adjustable ride control shock absorber in the off-road market. Engineered and manufactured in the U.S., this shock delivers a fully customizable damping experience for trucks, SUVs, and Jeeps used for on-road driving, off-road adventures, towing, and hauling.

Key Features:

• 9-Position Manual Adjustment: A simple turn of the external knob adjusts damping firmness across nine distinct settings — positions 1–3 mimic OE ride comfort, 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 position 1 to 9
• Large 2.75-Inch Tri-Tube Body: The oversized shock body increases fluid capacity and allows the shock to run cooler and more consistently, even under the most demanding conditions
• Nitrogen Gas Charged: Pressurized nitrogen minimizes air-to-oil mixture to reduce performance fade and foaming during extended use
• Heavy-Duty 18mm Nitro-Carburized Piston Rod: Provides increased scuffing resistance and superior corrosion protection for long service life
• 1-1/4-Inch 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 and trail conditions
• Rancho Red Polyurethane Bushings: Boost durability and ride performance compared to standard rubber bushings
• Protective Polyvinyl Boot Included: Shields the shock rod and oil seal from dirt, debris, and the elements to extend service life
• Premium Liquid Metallic Finish: Long-lasting corrosion-resistant coating for a clean, durable appearance
• Rod-Up / Body-Down Installation: Designed for easy, straightforward installation in the correct orientation

The RS9000XL shock also helps maintain consistent tire-to-road contact, improving steering, handling, and braking response. It resists vehicle bounce, body roll, sway, brake dive, and acceleration squat — making it an ideal upgrade for stock or lifted applications running larger tires and wheel combinations. Engineered and manufactured in the U.S.A. and backed by a Limited Lifetime Warranty (standard applications).
