- Large Shock Body (up to 2.75 inches): The oversized body helps the shock run cooler, delivering consistent performance even under demanding conditions.
- Nitrogen Gas Pressurization (120 PSI): Minimizes air-to-oil mixing, reducing fade and maintaining consistent damping performance by preventing foaming.
- Heavy-Duty Construction: Features an 18mm nitro-carburized piston rod to resist corrosion and scuffs, with double-welded loops for enhanced durability in stress areas.
- Temperature-Resistant Design: Built to handle extreme temperature changes, with an internal fluid that remains effective from -40°F to 248°F.
- Greater Durability and Protection: This product includes a polyvinyl boot to protect the shock rod and oil seal from damage and a premium liquid metallic finish for long-lasting durability.
Benefits of the RS999166:
- Customizable Ride Comfort: Nine positions allow you to adjust the damping to your liking, ensuring the exact balance of firmness and comfort, whether you're on the highway or off the beaten path.

- Extended Shock Life: With a self-lubricating seal and protective boot, these shocks are built to last and provide reliable performance over the long term.
