These 9.5" and 10" Nitro Pro Gears are manufactured from a proprietary material for maximum strength in competition/race vehicles. These gears are not intended for daily driven vehicles as they have a shorter life span relating to their wear characteristics. Please read the tech notes below and if you are unsure of what components you require or have question please call for clarification.

Tech notes:

  • 9.5/10" Nitro “Pro Gears" generally require an aftermarket housing with sufficient clearance for the larger diameter ring gear.
  • An aftermarket yoke will be required as these gears use a larger 35 spline pinion shaft than a standard 9 inch gearset
  • A different pinion support and bearings are needed to work with the larger diameter pinion shaft.
  • The cut on these gears is engineered for maximum strength and often these gears will run with significant noise compared with a traditional 9" gearset. This is normal for these gears as they are intended for competition use.


Warranty: Pro Gears are intended for Racing Fits and do not have a warranty as a result.
