Unorthodox Ultra Series gears are the pinnacle of adjustable cam gear technology. All the right engineering, giving you pure reliable performance! The gears set the industry standard for craftsmanship allowing each gear to be CAD designed and CNC'd from lightweight 6061-T6 billet aluminum. Each gear is adjustable in one degree increments to a maximum of +/- 10" (advance/retard). Any adjustment of the gear/s more than 10 degrees is useless, you may as well just skip a tooth during installation! Engine damage can happen to some cars after as little as 4 degrees. The engraved timing marks are accurate to within one (1) minute of a degree 60 minutes in a degree)! There is no such thing as having to send our gears to machine shop to be re-indexed properly! Other aftermarket gears can be off by as much as 1 or 2 degree!

*NOTE* This is PER Cam Gear and recommend buying the pair if the car is NON-VVTI.
