Frequently Asked Questions
What vehicles does the YG F8.8-411-15 fit?
This gear set fits 2015 and up Ford F-150 and Mustang models equipped with the Ford Super 8.8 inch rear differential. Always verify your axle code before ordering.
Is a ring and pinion install kit required?
Yes. A separate differential installation kit including bearings, shims, and crush sleeve or solid spacer is required. The ring and pinion set does not include these components.
Will YG F8.8-411-15 work with my factory limited slip differential?
Yes. The YG F8.8-411-15 gear set is compatible with the factory Torsen or open carrier, as well as most aftermarket lockers designed for the Ford Super 8.8 differential.
Does the Magnuson-Moss Warranty Act protect my vehicle warranty when I install this gear set?
Under the Magnuson-Moss Warranty Act of 1975, a dealer cannot void your factory vehicle warranty simply because you installed an aftermarket part. The dealer must prove that the aftermarket part caused the failure before denying a warranty claim.
What gear ratio should I choose for 35 inch tires on my 2015 F-150?
A 4.11 ratio is one of the most popular upgrades for 33 to 35 inch tires on the 2015 and up F-150, restoring performance and fuel economy close to factory levels.
What is the pinion spline count on YG F8.8-411-15?
The Ford Super 8.8 uses a 34-spline pinion shaft, which differs from the older Ford 8.8 inch differential. Confirm you have the Super 8.8 before purchasing this set.
How long does ring and pinion installation take?
A professional differential rebuild typically takes 3 to 5 hours. Proper setup with a dial indicator and bearing preload tools is essential for quiet, long-lasting operation.
Does this gear set come with a warranty?
Yukon Gear offers the Y.E.S. (Yukon Extended Service) protection plan for ring and pinion sets. This warranty covers defects in materials and workmanship and is transferable.
Installation Instructions

- Set pinion bearing preload per manufacturer specification using an inch-pound torque wrench.
- Install carrier assembly and set backlash between 0.006 and 0.010 inch.
- Verify gear pattern using gear marking compound before final assembly.
- Reinstall axle shafts, cover, and fill with the correct gear oil and friction modifier if applicable.
- Drive cautiously for the first 500 miles to allow proper gear break-in.
