Designed, dyno proven and made in the USA, Hot Cams performance camshafts are one of the most economical, reliable and easy to install ways to add a 5-10% power gain to your bike.
Stage 1: These cams provide better low RPM torque, pulling power, and throttle response.
Stage 2: These cams will provide improved full throttle torque and horsepower starting at 4000 RPM and up.
Tech Notes: This cam replaces the 2047-1IN. It has better low RPM torque, pulling power, and throttle response. For best results it should be used with the #2050-1E exhaust cam. Uses stock DRZ400 valve springs.

This handy tool will back off the cam chain tensioner mechanism and hold it for you. No more awkward 3-handed contortions are required to get the tensioner installed.
