Unleash your Polaris Predator 500's full rev potential with the Big Gun Rev Box. This plug-and-play ignition controller eliminates the factory CDI rev limiter, allowing your 2003–2004 Polaris Predator 500 to reach higher RPM for improved top-end power and faster acceleration in performance riding and racing applications.
Big Gun has built a reputation for quality powersports performance products, and the Rev Box is a cornerstone of their lineup. Unlike generic CDI boxes, Big Gun's Rev Box is calibrated specifically for the Predator 500's ignition curve, delivering smoother power delivery throughout the RPM range in addition to raising the rev ceiling.
The Big Gun Rev Box is a popular mod among Predator 500 owners looking for more top-end performance without expensive engine work. Shop all Big Gun ignition products and performance parts at Powersports Haven.
