INNOVATORS WEST 827 07-14 FORD SVT SHELBY GT500 10% OVERDRIVE HARMONIC BALANCER

Overdrive Balancer Assembly

2007-2014 GT500

Innovator's West PN 827 IF YOU WANT +15% 828 SEE ITEM # 390655972671

Manufactured in the USA by Innovator's West, this balancer installs directly in place of the factory unit.  It is precision-machined for a 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, also listed in this section.

Note 1:  A longer supercharger belt is needed when installing this overdrive balancer. The Gates K100852 (or equivalent) is recommended for use with the +10% balancer. 

Note 2:  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.
