Our camshafts are CNC machine ground from the absolute finest quality Billet Bar Stock for the highest degree of strength and precision. After the blanks are machined to size, they are sent to Yoshimura Japan for special metallurgical treatments. The next steps are grinding to absolute specifications, checking meticulously for accuracy, and finally heat-treating the finished camshafts for lasting performance. After final approval, the camshafts are sent back to Yoshimura USA for final packaging and sale.
R&D designed the camshaft with increased lift and duration to produce a potent curve with mid to top-end power & torque to accompany the power already available on the bottom end. This means when you whack open the throttle out of a corner, you'll get a nice hit off the bottom and an even bigger kick on the top end.
These Drop In Camshafts require no springs or shims for easy installation. This kit includes a Yoshimura camshaft, sprocket flange, bearing, and detailed installation instructions.
* Cam timing should be set by a certified mechanic to ensure proper function. Improper installation or cam timing could result in catastrophic engine failure.
