Our Camshafts are made from the highest quality Billet and CNC machine ground to perfection. Most Yoshimura camshafts are designed for our race teams, and in turn that design gets passed down to our customers for the best power gains. Some camshafts are direct drop-ins while other may come with shims or a complete spring kit to achieve proper valve spring pressure so no valve float occurs.

* Cam timing should be set by a certified mechanic to ensure proper function. Improper installation or cam timing could result in catastrophic engine failure.
