Metco Motorsports MIW0001 Overdrive Balancer Assembly

Manufactured in the USA by Innovator's West, this balancer installs directly in place of the factory unit. It is precision-machined for precise fit and perfect balance, and at only 11 lbs it removes significant rotating weight from the front of the crankshaft.

The pulley ring that drives the supercharger measures 7.950" (+10%) for part number 827, and 8.130" (+15%) for part number 828. This additional size provides an approximate gain of 3-4 lbs of boost for the +10% unit and 4-5 lbs for the +15% unit. A new heavy-duty balancer bolt is included.

This overdrive balancers work exceptionally well with our 2.60" supercharger pulley and auxiliary idler kit.

Notes:

• A longer supercharger belt is needed when installing this overdrive balancer. The Gates K100852 (or equivalent) is recommended for use with the +10% balancer.
• Some filing of the casting on the front cover is necessary to provide clearance to allow for the larger diameter of these balancers. The +15% OD balancer cannot be used on the 2013-2014 cars with the Track Pack option.
