  1. ATI 918046 15% Overdrive Harmonic Balancer (2007-2014 Shelby GT500)

    ATI 918046 15% Overdrive Harmonic Balancer (2007-2014 Shelby GT500)

    $568.16

    The patented ATI Super Damper is the only damper designed exclusively for high performance Ford engines.
    • Eliminates torsional crankshaft vibrations
    • Exceeds SFI 18.1 specs
    • Laser engraved 360* timing marks
    • Black zinc chromate finished
        Inner and outer shells are available in aluminum or steel, and contain a steel inertia weight. This inertia weight has six (2-ring design) or eight (3-ring design) computer machined grooves to retain the proper durometer O-rings (dyno tested for each application).

        NOTE: Installation of a new balancer bolt is REQUIRED as the factory Ford bolt is torque-to-yeild. Lethal Performance offers the bolts HERE. Also, cars equipped with the "Track Pack" option that has the factory oil cooler, the 15% OD balancers will not fit unless you modify the lower oil cooler hose OR delete the cooler all together. The 10% OD is better suited for Track Pack cars that want to keep the cooler.

  2. Innovators West 07-14 Shelby GT500 10% Overdrive Balancer w/Belt

    Innovators West 07-14 Shelby GT500 10% Overdrive Balancer w/Belt

    $799.00

    Innovators West Shelby GT500 10% Overdrive Balancer with Belt



    NOTE: The longer belt that's included in this kit is extremely hard to locate. This is why we now offer the option to buy the balancer and belt together making it easier to complete the installation of this part.In addition to the belt we include a longer than stock M12 bolt for installing the balancer, and the three M10 bolts that are needed if you ever remove this balancer.

    Innovators West now offers a complete replacement balancer for the 2007-2014 5.4L & 5.8L Shelby GT500.

    Ford redesigned the factory balancer for 2008, making it much lighter than the 2007 unit. This balancer is even lighter than the new 2008 part.

    -The supercharger drive section of the pulley is enlarged in diameter by 10%, for a 3-4psi increase in boost.
    -Improves performance by reducing rotating weight and raising supercharger boost.
    -Great for Ford Racing TVS blowers and those looking to get the most out of their stock blower.
    -Available as 10% OD
    -10% OD balancer requires slightly filing of casting for clearance.
