Why choose this set

• Restores lost performance from larger tires or heavy loads without sacrificing smooth drivability.
• Yukon’s manufacturing tolerances and matched gear sets reduce noise and improve longevity when installed correctly.
• Ideal for tow rigs, daily drivers with upgraded tires, and performance builds that need a dependable, application-specific ratio.

Fitment & installation notes

• Confirm your axle: this set fits Ford 9.75" (2011+) housings with a 12-bolt ring gear pattern.
• Verify pinion spline count (31) and your axle spline count before ordering — some Ford 9.75" applications use different spline counts (confirm with your VIN or axle tag).
• Mounting hardware, bearings, and shims are not included; plan to source these or use an installation kit.
• Proper setup requires correct pinion depth, bearing preload, and backlash — professional installation or a qualified shop is strongly recommended for quiet, long-lasting performance.
