If you have done some serious tuning to your engine, you may find that you need to work on the cams. If you want to increase your power, versatility, and reliability, than you need to install a set of AEM cam gears. AEM cam gears are designed for vehicles that have engines that are either milled, high compression, or have forced induction intake systems. The AEM cam gears are designed to be adjustable with changes as precise as one degree. AEM makes this possible by etching their cam gears with precision lasers, giving you the flexibility to make the tiniest changes for the most precise tuning possible. The AEM cam gear teeth are precision cut and anodized hardened to ensure reliability and to also reduce premature wear on the belts. With the AEM cam gears, you can match the timing of the intake and output valves to the most precise increments, allowing you the same flexibility in tuning that race cars have. You can also tune more quickly with the AEM cam gears without having to change out an entire camshaft, a proposition that is both complicated and expensive.
