Jackal Motorsports 57mm Press-on 3.0T Supercharger Pulley

Jackal Motorsports is now offering our very own Stainless Steel 57mm Press-On Supercharger Pulley for the Gen 1 EA837 3.0T supercharged vehicles.

So what makes this pulley different?

Unlike many smooth-surface pulleys on the market, our 57mm pulley features a rough etched belt surface specifically designed to help improve belt grip and reduce belt slip under high load and aggressive boost conditions. Similar to the proven design used on our lower crank pulleys, the etched surface helps the belt maintain better contact with the pulley, especially at higher RPM where slip can become a common issue on upgraded setups. Better grip means more consistent boost performance and improved reliability when pushing your 3.0T harder.

 

The 57mm upper pulley allows you to run most Stage 2 software setups with excellent drivability and performance gains.
