PHR is proud to introduce our new Billet Cam Gears for the 2JZ and 1JZ engine familes. Adjustable cam gears are important for dialing in opening and closing events on camshafts as well as lobe centerline. You camshaft was designed to target these specific events and you need an adjustable cam gear to adjust them as close to your specifcations and requirements as possible. Beyond that, you may be able to find additional horsepower or tweak your power curve to your specific needs by adjusting the valve timing with these gears. PHR Cam Gears also offer an engine dress aspect that looks amazing in your engine bay and pairs perfectly with PHR's accessory pulley kits. PHR's Cam gears are cut from 6061 billet aluminum. The outer gear is hard anodized black to take any abuse that will be given them. All hardware is stainless steel and will never tarnish or rust. VVT-i model engines will require only one gear, as the intake gear cannot be replaced for VVT-i to remain operable. Price is per gear.
