Improve the performance in your vehicle by replacing your factory crank pulley with the COBB Tuning Lightweight Main Pulley. This particular pulley has been fabricated from billet 6061-T6 high-grade aluminum, and it has been anodized black to provide extra protection against rust and corrosion,
Lightweight crank pulleys reduce rotational mass without affecting the balance of the flat 4 motor. This pulley is almost 4lbs lighter when compared to the factory unit and the result is improved throttle response while maintaining the factory pulley diameter to help with installation. Pulley weight is 1.2 lbs.
