Yukon Ford 10.5" Ring & Pinion Gears - 2011+, 37 Spline
YG F10.5-331-37
The Yukon Gear & Axle Ford 10.5" Ring & Pinion Gear Set is a matched gear set for 2011+ Ford 10.5" rear differentials using a 37-spline pinion. Available ratios from 3.31 through 4.88 allow the axle gearing to be matched to tire size, drivetrain setup, towing requirements, or the intended use of the vehicle.
Each set includes a matched 10.5" ring gear and pinion with a 12-bolt ring gear configuration. Installation requires proper pinion depth, bearing preload, and backlash setup, so verify the axle platform, 37-spline pinion configuration, and desired gear ratio before ordering.
Includes:
- (1) Ford 10.5" Ring Gear
- (1) Matching Pinion Gear
Note: Bearings, races, shims, seals, and other differential installation components are sold separately unless specifically included elsewhere in the selected package.

- For custom axle builds and swaps, identify fitment by the Ford 10.5" axle configuration rather than the vehicle application.
FAQ
What Ford axle does this ring and pinion fit?
This gear set is designed for compatible 2011+ Ford 10.5" rear differentials using a 37-spline pinion configuration.
What gear ratios are available?
Available ratios are 3.31, 3.55, 3.73, 4.11, 4.30, 4.56, and 4.88.
Does the gear set include installation bearings and shims?
No. The listing includes the matched ring and pinion gears. Bearings, shims, seals, and other installation components are sold separately unless otherwise specified.
Can this gear set be used in a custom Ford 10.5" axle build?
Yes, when the axle uses the compatible Ford 10.5" rear differential and 37-spline pinion configuration. For custom builds, axle identification is more important than the original vehicle application.
What needs to be set during ring and pinion installation?
Ring and pinion installation requires proper pinion depth, bearing preload, and backlash. These settings should be established during differential assembly for the selected gear set.
