Kit comes with everything you need to upgrade the stock timing belt tensioner on 1.8t. Everything was packaged nice, and made from good quality materials. The reason I decided to do this, the stock hydraulic tensioner pulley started making noise on cold startups, and instead of replacing it with an already poorly designed factory tensioner I decided to upgrade. Which fun fact, VW decided the original design was poor too and superseded the part with a similar setup like this kit. You get the added reliability, easier installation, and piece of mind of a better design to a very important aspect to your engine. Can’t go wrong with this kit if it’s that time to do your timing belt!
