Key Features:
The Rancho RS9000XL shocks combine advanced technology and robust construction to meet the demands of hardworking trucks and off-road enthusiasts. Key features include:
- Nine-position adjustable damping: Easily customize ride firmness and control with a simple manual knob, adapting to on-road comfort or off-road performance needs.
- Tri-tube body design: Up to 2.75-inch diameter tri-tube construction filled with all-weather fluid ensures cooler operation and consistent damping in temperatures from -40°F to 248°F.
- Durable piston rod: Application-specific 18mm nitro-carburized piston rod resists scuffs and corrosion for long-lasting reliability.
- Enhanced structural integrity: Double-welded loops at stress points and a 1.25-inch sintered iron piston provide superior strength under heavy loads.
- Low-friction seals: Self-lubricating seals retain gas and oil to enable quicker rebound and smoother compression for improved ride quality.
- Protective finish and boot: Premium liquid metallic coating combined with a polyvinyl protective boot extends shock life by guarding against dirt and debris.
- Ride comfort enhancements: Polyurethane rebound bumper and bushings along with graphite-filled fluon-banded piston reduce harshness and improve responsiveness.
- Nitrogen gas pressurization: Pressurized to 120 PSI to minimize air-to-oil mixing, reducing damping fade and foaming during demanding use.
- Industry first: The RS9000XL was the pioneering nine-position manually adjustable shock absorber in the off-road market.
Construction & Design:
Rancho engineered the RS9000XL shocks with a focus on durability and performance under extreme conditions. The tri-tube body design enhances heat dissipation, preventing shock fade during prolonged use. The nitro-carburized piston rod offers exceptional resistance to wear and corrosion, critical for off-road environments. Double-welded loops reinforce high-stress areas, while the sintered iron piston ensures consistent damping force. Low-friction, self-lubricating seals maintain internal pressure and fluid retention, contributing to smoother operation and longer service life. A premium liquid metallic finish and protective polyvinyl boot shield the shock from environmental damage, extending durability in harsh conditions.
