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. Our gears start out as a solid block of steel and get precisely machined into the finished piece, with special attention taken to the area where the gear meets the crankshaft. Our billet replacement offers a press-fit, so the gear is no longer loose on the end of the crankshaft, eliminating any chance of the gear coming loose and shearing the keyway. We finish them with a bright zinc plated finish to prevent against corrosion. These gears feature the 4-bolt damper interface, so they are a direct fit for all 06A 1.8T engines.
