GFB Lightweight Non-Underdrive Crank Pulley Audi A3, S3 8P/TT 8J/VW Golf GTI Mk5/Golf R Mk6 (2.0 TFSI)

Purpose-built performance

The GFB Lightweight Non-Underdrive Crank Pulley Audi A3, S3 8P/TT 8J/VW Golf GTI Mk5/Golf R Mk6 (2.0 TFSI) is a lightweight crankshaft pulley selected for its role in the engine accessory drive. This replacement crank pulley is intended to reduce pulley mass while preserving the specified drive ratio. As a non-underdrive design, it aims to retain factory accessory speed rather than slowing driven accessories as part of a ratio change. Unlike a generic replacement part, selecting the correct version matters for connection geometry, operating behaviour and the intended vehicle or custom installation.

How it works

Confirm installation clearances and the specification of the original assembly before fitting. The replacement should be evaluated as part of the complete vehicle system rather than assuming an automatic horsepower gain.
