Ring & Pinion Pro Ford 10" Reverse Shot Peened 4.57 Ratio

Ford 10" Off-Road High Performance 5.14 Reverse Nitro Ring & Pinion

The “10 Inch.” variant of the Ford 9” has been used by some of the worlds top drag cars, Ultra4 cars & Desert Race / Trophy Trucks. Most other 10” gears are made of a softer material for short bursts, but will not last for long distance. The new Nitro Pro Series 10” ring & pinions are manufactured from a proprietary blend of the best materials and precision cut, lapped and heat treated with state-of-the art processes. Each gearset is also shot-peened, which provides added protection from superficial stress cracks and imperfection, as well as alters the properties of gear's surface for added strength and durability. Nitro Pro Series 10” gears are made for hardcore and competition applications, but unlike most other 10” gears, are made for weekend warrior street vehicles as well.

Tech notes:

Works with Gear Works High Pinion 10”

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 to a traditional 9" gearset. This is normal for these gears as they are intended for competition use.
