Rancho RS994278 RS9000XL 9-Position Adjustable Shock Absorber

The Rancho RS994278 is part of the legendary RS9000XL series — Rancho's premium 9-position manually adjustable shock absorber designed for trucks, SUVs, and off-road vehicles. Whether you're hauling heavy loads, towing a trailer, or hitting the trails, the RS9000XL lets you dial in the exact ride quality you need with a simple twist of the external adjuster.

Key Features:

• 9-Position Manual Adjustability: Easily tune damping from soft (daily comfort) to firm (off-road performance or heavy loads) without any tools
• Monotube Design: Large-bore, single-tube construction provides superior heat dissipation and consistent performance under demanding conditions
• Nitrogen Gas-Charged: Pressurized nitrogen charge prevents aeration and fluid foaming for fade-free performance
• Heavy-Duty Piston: Large-diameter piston and precision-valved internals deliver a broad range of damping control
• Durable Construction: Features a zinc-dichromate protective coating on the body and chrome-finished piston shaft for corrosion resistance
• OEM-Style Mounting: Direct bolt-on replacement using factory mounting hardware and locations — no modifications required
• Rancho Warranty: Backed by Rancho's limited lifetime warranty

The RS9000XL RS994278 is engineered as a direct-fit replacement shock that delivers the versatility of an aftermarket performance upgrade without sacrificing everyday drivability. It is ideal for lifted vehicles and is compatible with Rancho's full line of suspension lift kits.
