Product Details
If you're looking to get a little more out of your Honda TRX 300EX, swapping out the stock CDI box for an aftermarket rev box is a common way to do it. This Big Gun Over Rev Box is a well-built alternative to pricier OEM replacements, designed to give you more performance without breaking the bank.
This rev box works by increasing the overall RPM limit your engine can reach, and it also advances the timing curve. What that means for you is improved throttle response and a bit more power available at higher engine speeds. It's a direct plug-in replacement for your stock CDI box, so installation is straightforward – no complex wiring or modifications needed.
While this unit isn't CARB approved and can't be shipped to California, it's a solid option for riders looking to unlock a bit more performance from their TRX 300EX.
