Eliminate the concern of shearing your 1. 8T timing drive gear keyway once-and-for-all with this billet replacement. The factory gears are notorious for coming loose in high rpm conditions, leading to the keyways completely breaking, causing timing belt failure. Along with that, we have seen failures from the powdered metal gears completely disintegrating from small cracks that develop as the bolt is torqued. As a result from these failures, valves bend and pistons become damaged. We offer dowel pin gear kits and arp crank bolts to help this situation, but they do not eliminate the poorly constructed factory timing gear. With that in mind, we found ourselves back at the drawing board. We knew that there was a better solution for that problem it would just take some serious work and testing to bring it to the market. With this product, we have completely redesigned the factory interface, removing the weak factory gear and loose-fitting keyway, replacing it with a solid steel gear with a press-fit interface.
