Hot Cams is a industry leader when it comes to the research, design, development and improvements in the field of aftermarket high performance and racing ATV camshafts. Hot Cams provide new performance ATV cams and they do not require a core exchange. This is a great time save as you can keep your ATV running right up to the time you are ready to install your camshaft. No having to deal with camshaft exchanges and extra waiting while parts are shipped back and forth.
Whatever type of riding you enjoy, whether it is cruising around on trails or serious all out ATV racing Hot Cams has a high performance or racing cam to improve the torque and horsepower of your engine. HotCams
provides the atv cam you need for superior horsepower and torque from an easy to install atv camshaft.
HotCams produces a premium quality ATV cam that provides a great dollar per horsepower improvement. Hot Cams provides simple parts replacement, gains in performance and is one of the best ATV performance parts improvements available for the money. Often times people will spend far more on other external parts such as a new silencer or full exhaust system only to gain less performance for a much greater expense than the gains found with a HotCams ATV cam.
Hot Cams ATV camshafts come with OEM de-compression mounts in the camshaft, or if the OEM part is not removable from your stock atv camshaft then the required de-compression parts are included with your new Hotcams camshaft.
Do you want crave even more power? Then we recommend you also switch to a high performance forged piston from CP Pistons. Our listing of CP ATV pistons is available here.
