The camshaft on any 4-stroke engine is the #1 ingredient to adding serious horsepower. The staff at Hot Seat Performance and Speedwerx have put in countless hours of designing, testing and development into the design of each of these camshafts to ensure that you not only get the most power gains available, but your machine remains safe and reliable at the same time. Each of our camshaft kits come with complete installation and break-in instructions. We also send proper gaskets for applications that require different thickness gaskets than stock. For best overall results we highly suggest our cylinder head porting along with any camshaft kit.

NOTE: When purchasing a camshaft you will be billed for the Grind and the stock camshaft core. We will issue you a credit when you send in your stock camshaft core! (You will have 2 weeks to return the core for full credit.)
