• Double-welded loops and sintered iron piston: Reinforced stress points and a 1.25-inch piston enhance structural integrity under heavy loads.
• Low-friction, self-lubricating seal: Retains gas and oil for quicker rebound and smoother compression cycles.
• Polyurethane rebound bumper and bushings: Absorb harsh impacts and improve ride smoothness.
• Nitrogen gas pressurized to 120 PSI: Minimizes air-to-oil mixing, reducing shock fade and foaming during extended use.
• Protective polyvinyl boot and premium liquid metallic finish: Shield the shock from dirt, debris, and corrosion for extended service life.

Construction & Design:

The RS9000XL is engineered with a robust tri-tube body that balances strength and heat dissipation, ensuring reliable performance in extreme environments. The nitro-carburized piston rod undergoes a specialized hardening process to resist wear and corrosion, critical for off-road durability. Double-welded loops at high-stress points and a heavy-duty sintered iron piston provide enhanced structural integrity, making this shock absorber capable of withstanding the rigors of towing, hauling, and aggressive off-road driving.

Additionally, the shock’s low-friction, self-lubricating seal design maintains internal pressure and fluid retention, which contributes to consistent damping and longer service intervals. The polyvinyl protective boot guards against contaminants, while the liquid metallic finish offers corrosion resistance and a professional appearance.
