Specifically, the FOX Rear Adventure Shocks offer impressive reliability and consistent functionality over your stock rear shocks, giving you a boost of confidence every time you're behind the wheel. Additionally, these shocks deliver improved rear-end handling and control whether you're towing a heavy load, challenging new terrain, or simply running errands in the city. This is achieved by FOX's proven damping technology to provide a comfortable on-road ride and predictable off-road handling in a variety of situations. 6061-T6 Aluminum Shock Body with Monotube IFP Design The FOX Rear Adventure Shock was built around a massive, 2" diameter 6061-T6 aluminum shock body that provides superior strength for long-lasting functionality without compromise. FOX paired this hardcore shock body with an equally impressive 5/8" hard chrome plated, heat-treated alloy steel shaft that adds another layer of durability for extreme applications. Moreover, the shock's monotube design utilizes an Internal Floating Piston (IFP) to separate the shock oil from the high-pressure nitrogen gas chamber, resulting in consistent damping performance every single time. The shock oil used is JM92 advanced suspension fluid that makes for faster heat dissipation so you can continue tackling your favorite terrain with more confidence in tough situations. Installation has been made simple and straightforward as this rear shock installs directly in place of your factory components. The FOX Rear Adventure Shock is sold individually, you'll a total of 2 for a complete set!
