Innovators West has provided ring & pinion lightening for most popular drag racing gears for a number of years. The lightening process combines a lightening operation on the back side of the gear as well as a pocket milling procedure to lighten in between the ring gear bolts (where applicable). The lightening procedure maintains a minimum gear thikness in order to provide the lightest gear while maintaining needed strength. Lightened gears have been used in everything from NHRA Stock to IHRA Pro Mods.

Service Q & A

  • Can all types of ring & pinion gears be lightened?
    Innovators West has fixtures for the following gears:
    Ford 7.5"
    Ford 8.8"
    Ford 9"
    Ford 9.5"
    GM 12-Bolt
    Unfortunately due to our current work load we are not able to lighten gears other than those listed above at this time. Innovators West does not lighten any gears other than the listed ring & pinion gears. Innovators West does not lighten spools.

  • Does the lightening process make the ring gear weaker?
    Yes - anytime you reduce mass like this it will increase deflection in the gear. How much impact it will have on your ring gear life will depend on your application. We do maintain a minimum thickness when machining to avoid deflection, and in most cases you will not likely see a reduction in service life.

  • How much will this help lower ET's?
    By itself, reduced weight of the ring gear might not be noticeable on the ET slip, but in combination with other reductions in rotating and non-rotating weight, eventually these modifications when added together have an significant impact. It's well understood that ET is a function of car weight and horsepower, this is one of those every little bit helps, and due to the diameter of the ring gear, it can have more effect than say gun-drilled axles.

  • What's the turn around time to have this done?
    Typical turn around time is about 3 to 4 weeks.

  • When will I be billed?
    An Innovators West employee will contact you for billing on your Credit Card (Amex/Visa/MC) when the parts are ready to ship.
