Key Features:

The Rancho RS9000XL shock absorber incorporates advanced technology and robust construction to deliver consistent, customizable performance:

• Nine-position adjustable knob allows tailored damping control for on-road comfort or off-road firmness.
• Up to 2.75-inch tri-tube body filled with all-weather fluid ensures cooler operation and reliable performance in temperatures ranging from -40°F to 248°F.
• Application-specific 18mm nitro-carburized piston rod resists scuffs and corrosion for extended durability.
• Double-welded loops at stress points and a 1.25-inch sintered iron piston enhance structural integrity under heavy loads.
• Low-friction, self-lubricating seal retains gas and oil, enabling quicker rebound and smoother compression.
• Polyurethane rebound bumper and bushings combined with a graphite-filled fluon-banded piston reduce ride harshness and improve responsiveness.
• Nitrogen gas pressurized to 120 PSI minimizes air-to-oil mixture, reducing damping fade and foaming during extended use.
• Protective polyvinyl boot and premium liquid metallic finish extend shock life by guarding against dirt and corrosion.

Construction & Design:

The RS9000XL is engineered with a robust tri-tube design that balances strength and heat dissipation, critical for maintaining consistent damping performance under demanding conditions. The nitro-carburized piston rod offers superior surface hardness to resist wear and corrosion, while the sintered iron piston ensures durability and precise control. Double-welded loops reinforce high-stress areas, preventing premature failure during heavy-duty use.

Seals are crafted to reduce friction and retain internal fluids, promoting faster shock response and longer service life. The shock’s exterior is protected by a liquid metallic finish and a polyvinyl boot, shielding vital components from environmental damage and debris.
