Our camshafts are made in Japan from premium materials. Other companies offer you their camshafts and require you to purchase springs and other items. Not us. Out kits come complete and there's no need for additional purchases. Also, using the our kit springs will insure the best reliability and performance. Our cams are precision ground from billet blanks using high -tolerance equipment, not welded and reground. When performance counts, trust Yoshimura.

• Precision ground billet camshafts
• Springs are matched to the profile to maximize performance and reliability
• Adjustable intake cam gear
• Fixed exhaust cam gear
• Valve springs and seat shims
• Increased lift and duration to produce a potent curve with mid to top-end power & torque
