IE Billet Adjustable Camshaft Gear Ultimate Kit for VW/Audi 1.8T 20V Engines

IE's Adjustable Cam Gear allows you to finely tune the power band of your engine by advancing or retarding your cam timing. This adjustment allows you to dial in whatever cams you have to the setup you are running for peak power. Each cam gear is precision CNC machined from solid 6061 aluminum and features a real one-piece male keyway for an exact OE fit. The cam gear outer rings are machined to OE specifications for a perfect mesh with your timing belt and then hard anodized for wear. The threads are roll form tapped to create the toughest threads available and then stuffed with high-quality stainless ARP bolts to lock it all together. Finally, a flawless layer of bright dip anodizing is interrupted only by the crisp laser etching which ensures you can always know exactly where your cams are positioned.

With the added stress of larger cams and stiffer valve springs, the factory interface can become weakened and fail under high RPM use. The ARP Bolt greatly increases the clamping force, holding it firmly in place. The friction disk increases the grip between the cam gear and cam, preventing sheared keyways, especially used in conjunction with the upgraded bolt.
