Toyota 1JZ / 2JZ Cam gears have been CNC machined from highest quality 6061 T6 aluminium to more precise tolerances than original OEM gears. The tooth edges have been bevelled to increase belt life and then hard anodised to ensure strength and longevity. Precise degree markings are then laser etched onto the cam gear to assist in the tuning of engines. To finish we have used high quality fasteners and a heli-coil thread insert in the ring gear to allow enough torque to be applied while tightening fasteners. They can be adjusted multiple times with confidence that the threads will not stretch or fatigue.
