Hop-Up Kits for Kart Racing

Hop-up kits are 100% complete kits with all parts needed to enhance your kart’s performance (engine not included). All kits require an aftermarket exhaust and/or header in order to work properly and get you the expected horsepower. The exhaust is not included and must be ordered separately. Horsepower ratings are for reference only and are based on a system with a tuned exhaust. Actual HP may be different.

Improve your vehicle’s performance with go-kart racing kits for some of the most popular models in kart racing. We have kits that are compatible with the Honda GX series, Chinese OHV, Predator engines, and more. Get maximum performance from stage one to four with kits made from stock parts for the best fit. Improve reliability and power even further with stage two hop-up kits that include a bored carb and cam so you can get the most out of your vehicle. Take the upgrades even further to stage three with a billet rod and gasket to get even more horsepower out of your engine. Finally, we offer the peak of racing go-kart kits, the stage four hop-up kits. Achieve peak performance with the addition of ported and milled heads, stainless valves, billet rockers, and a heavy-duty cam package. These kits are more customizable than the previous stages and allow you to build a motor exceeding 20 horsepower.
