Innovators West - 07-11 Mustang Shelby GT500 Innovators West 10% or 15% OD balancer

Innovators West now offers a complete light-weight replacement balancer for the 2007-2011 5.4L Shelby GT500. We run this balancer on our own Red/Silver 2007 GT500.

This is the same pulley that other vendors call the "4lb lower" and market it as their own, even though its actually made by Innovators West. The supercharger drive section of the pulley is enlarged in diameter by 10%, depending on the blower you are using, you'll see at least a 2.5psi increase in boost, and sometimes 3-4psi total.

Also improves performance by reducing rotating weight.

Great for Ford Racing TVS supercharger / blower upgrade M-6066-SGT and those looking to get the most out of their stock blower. It's possible to make 18-19PSI with the FRPP TVS, when combined with the VMP 2.59" upper pulley.

Available as 10% OD or 15% OD, requires clearancing of tab to fit.

SFI approved. An SFI approved balancer is required by NHRA and IHRA for vehicles running 10.99 or quicker.

The longer belt needed with the OD pulley is extremely hard to locate, and available with this package for an additional $50 standard or $80 green heavy duty (recommended).

To make it easier for the customer, we include a longer than stock M12 bolt for installing the balancer, and three M10 bolts that are needed to remove the stock 07 balancer. Please see our article below for complete installation information.
