The FOX Float 3 EVOL RC2 Front Shocks Kit is a race-focused suspension upgrade designed for sport and competition ATV applications. This kit fits 2009–2017 Yamaha YFZ450R models, including the 2009 Yamaha YFZ450R SE. Manufactured by FOX and supplied under vendor part number 830-24-245, the kit uses an ultra-lightweight air-spring design to reduce weight compared with conventional coil-spring shocks while delivering responsive, tunable performance.
External rebound adjustment lets riders control how quickly the shocks return after compression, helping optimize handling across changing terrain and riding conditions. The high-flow high- and low-speed compression adjuster provides an expanded adjustment range, while race-proven velocity-sensitive damping technology uses application-specific piston flow designs and valving for consistent control. The infinitely adjustable MAIN air chamber produces a progressive spring rate, and the EVOL air chamber allows precise tuning of roll, cornering response, final-stroke spring rate, and bottoming resistance.
