The perfect gear for your Audi S3 and Audi TTS Our 2.0 TFSI billet RACE timing belt drive wheels (for Audi S3 and TTS, among others) are the perfect connection to the crankshaft. Tuning fans in particular will get their money's worth with this crankshaft gear, because you'll never have problems with worn-out gears again! The screw connection of the crankshaft sprocket to the crankshaft is known to be a major weak point in VW and Audi engines. The original crankshaft sprocket can no longer cope with engines with increased performance: The guide groove can shear off on the crankshaft and quickly lead to major engine damage. To prevent this from happening, you should upgrade your Audi S3 or Audi TTS with our Race crankshaft gear. It is milled from solid material and therefore very robust. The wheel is heated before fitting. Thanks to this press fit, it sits perfectly on the crankshaft and - unlike the standard part - does not allow any tolerances. It is galvanised against corrosion and is supplied with new screws. With our gear you can enjoy the full performance of your 2.0 TFSI engine without fear of damage! Together with our ARP main bolt and friction disc , maximum durability is achieved! Features of the BILLET crankshaft sprocket: Milled from the solid Press-fit (heated before assembly) Galvanised to protect against corrosion Includes 6 new screws Installation tips: Heat the billet sprocket on a hotplate and then pre-install it together with the friction disc and an original screw. Then remove the original screw and fit our ARP main bolt. This ensures perfect wheel retention. No more problems with worn out gears!
