PHR and SupraStore are proud to introduce their new Billet Cam Gears for the 2JZ and 1JZ engine families!
Adjustable cam gears are important for dialing in opening and closing events on camshafts, as well as lobe center-line. You camshaft was designed to target these specific events, and you need an adjustable cam gear to adjust them as close to your specifications 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. If you have a non-VVTi engine, you can select from the "single cam gear" options. Otherwise, you will need to select from "both".
The Powerhouse Racing Billet Adjustable Locking Cam Gears are the only gears in the world for the 2JZ that offer a way of locking the gear and absolutely eliminating any chance of slip. See the video below. The PHR Gear comes with the 0 position lock which will be the most widely used position. For those wanting to adjust their cam timing, the PHR adjusting kit is available. This kit allows adjustment from 1 degree to 9 degrees positive or negative and assures that your gear CANNOT SLIP FROM ITS ADJUSTED POSITION!
INSTALLATION NOTE FOR 1JZ ENGINES
Depending on camshaft manufacturer, it is necessary to replace the bolts on your back plate to button head bolts to keep cam gear from rubbing the factory hardware. Please check rotation of the gear prior to installation and replace hardware if necessary.
