Rancho RS999838 RS9000XL 9-Position Adjustable Suspension Strut Assembly

The Rancho RS999838 RS9000XL Suspension Strut delivers nine individually selectable damping levels, making it one of the most versatile and driver-configurable struts available for trucks, SUVs, and Jeeps. Globally recognized as the first nine-position manually adjustable ride control series in the off-road market, the RS9000XL is engineered to perform whether you're commuting on pavement, tackling off-road trails, or hauling a heavy load.

Nine Levels of Adjustable Performance:

• Positions 1–3: Softer, more compliant tuning optimized for everyday on-road and light off-road flexibility
• Positions 4–6: Mid-range damping comparable to RS5000 performance levels
• Positions 7–9: Firm, maximum-control settings ideal for towing, hauling, and aggressive off-road driving

Key Features:

• Triple-tube (tri-tube) gas-pressurized design — Large 2.75-inch body increases fluid capacity to run cooler and more consistently under demanding conditions
• 18mm nitro-carburized piston rod — Application-specific Nitro-Carb treatment resists scuffing and corrosion for long-term durability
• 1-1/4-inch sintered iron piston — Double-welded stress points and sintered iron construction enhance structural integrity
• Graphite-filled, Fluon-banded piston — Provides smoother piston travel and greater damping responsiveness
• Nitrogen gas pressurized to 100 PSI — Minimizes air-to-oil mixture to reduce fade and foaming during extended use
• All-weather fluid with low-friction, self-lubricating seals — Enables quicker rebound and smoother compression throughout the strut cycle
• Liquid metallic finish with protective red boot — Delivers a premium appearance with added protection
• Sold individually

The RS9000XL's adjustable damping directly counteracts the additional unsprung mass that comes with larger tire and wheel combinations, helping maintain consistent tire-to-road contact for improved steering, handling, and braking. Engineered and manufactured in the U.S., each RS999838 strut is backed by Rancho's Limited Lifetime Warranty and a 90-Day Free Ride Offer.
