Construction & Design:

The RS9000XL shocks are engineered with a robust tri-tube design that enhances heat dissipation and shock fluid stability, ensuring reliable operation even under extreme temperature conditions. The piston rod is nitro-carburized to resist wear and corrosion, while the sintered iron piston adds strength to withstand heavy-duty use. Double-welded loops at critical stress points reinforce the shock’s structural integrity, making it suitable for demanding off-road environments.

Additionally, the shock features a low-friction, self-lubricating seal that maintains internal pressure and fluid retention for smooth and responsive damping. The inclusion of a polyurethane rebound bumper and bushings further cushions impacts and reduces ride harshness, contributing to a more comfortable driving experience.
