Rancho RS994048 RS9000XL Nine-Position Adjustable Shock Absorber

The Rancho RS994048 is a RS9000XL Series nine-position manually adjustable shock absorber engineered for trucks, SUVs, and Jeeps that demand performance under the most demanding on-road and off-road conditions. Part of Rancho's fourth-generation RS9000XL platform, this shock delivers a significant upgrade in strength, durability, and damping precision over standard replacement units.

Key Features:

• Nine-Position Adjustable Damping: An easy-to-use external knob provides nine distinct levels of damping control, allowing drivers to dial in the ideal balance of firmness and compliance for everything from highway cruising to rough trail use
• Tri-Tube Body (up to 2.38 in.): The oversized tri-tube design filled with all-weather fluid allows for cooler operation and can withstand internal temperatures from -40°F to 248°F
• Nitrogen Gas Pressurized: Charged to 45 or 60 PSI (application specific) to minimize air-to-oil mixing, reduce damping fade, and prevent foaming under heavy use
• Polyurethane Rebound Bumper & Bushings: Absorbs ride harshness and improves responsiveness across changing road and trail conditions
• Graphite-Filled Fluon-Banded Piston: Enhances damping consistency and contributes to an overall smoother ride feel
• Low-Friction Self-Lubricating Seal: Retains gas and oil for quicker rebound and smoother compression throughout the life of the shock
• Integrated Bottom Mounts: Fourth-generation design feature that improves structural strength at the lower mounting point
• Dual Component 2K Paint Finish: Premium liquid metallic finish with superior chip resistance keeps the shock looking and performing its best long-term
• Polyvinyl Protective Boot: Guards the shock shaft against debris, dirt, and contamination for extended service life
• Limited Lifetime Warranty: Backed by Rancho's industry-leading limited lifetime warranty for added confidence

Designed specifically for hardworking full-size trucks and heavy-duty applications including towing and hauling, the Rancho RS994048 RS9000XL delivers the flexibility of a performance shock with the durability required for serious work and off-road use.
