Fox Factory announces new OEM side-by-side specification wins Fox Factory (FOXF) announced that FOX Performance Series 2.0 PODIUM X shocks are the stock suspension packages on two newly-released 2015 Polaris (PII) side-by-side models, including the high performance RZR S 900 and the trail RZR 900 XC Edition. Polaris completely redefined their original RZR 900 and RZR S 900 for 2015. Both vehicles feature a 75 horsepower ProStar engine that offers an improved power-to-weight ratio and faster acceleration. The RZR XP 1000 transmission is used to get more power to the ground with optimized gearing to take full advantage of the engine's power. Helping keep all of this power under control on the RZR S 900 and RZR 900 XC Edition are highly-capable, Dual A-Arm Front and Rear Suspension systems featuring FOX Performance Series 2.0 PODIUM X shocks.
