Product Details

If you've already got a KraftWerks supercharger kit on your 2013-2020 Subaru BRZ or 2013-2016 Scion FR-S, this 30mm boost upgrade pulley is a straightforward way to get a little more power.

This pulley is a direct replacement for the one that came with your original kit, making the installation process pretty simple if you're comfortable working around the supercharger assembly.

The core of the KraftWerks system uses a Rotrex traction-drive supercharger, known for its efficiency and ability to spin at high RPMs. This pulley upgrade leverages that design to push more air into your engine. It's a well-built component that's meant to integrate seamlessly with your existing KraftWerks setup, offering a practical way to extract more performance without needing to change out the entire supercharger unit.
