Mitsubishi EVO 4-9 Underdrive Crank Pulley Incl Belt [2011]

The GFB Under-drive Crank Pulley for the Mitsubishi EVO VIII & IX is designed to improve engine performance by reducing parasitic losses at high RPM. Made from durable 6000 series aluminium alloy billet, this pulley offers a significant weight saving of 1.4 kg over the factory pulley, without sacrificing strength or reliability.

The kit comes with everything needed for installation, including the serpentine belt, and it can be fitted in as little as 30 minutes with no specialized tools required. The accessories are under-driven by 20%, which helps the engine feel more willing to rev, particularly off-boost. This results in sharper throttle response and a more responsive engine, especially at higher RPM.

This lightweight under-drive pulley is an ideal modification for improving throttle response and overall engine performance on the EVO VIII & IX, making the car feel livelier without compromising accessory performance at lower RPM.
