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
- Drain differential fluid and remove the axle shafts and differential cover.
- Mark the bearing caps and remove the carrier assembly from the housing.
- Press off old ring gear and thoroughly clean the carrier flange.
- Install new ring gear from YG F8.8-411-15 and torque bolts to specification in a cross pattern.
- Remove old pinion gear, crush sleeve, and pinion bearings from the housing.
- Press new pinion bearings onto the pinion shaft.
- Install new crush sleeve and set pinion depth using shims and a dial indicator.
- 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.

Final Drive Gears
Final drive gears determine the overall multiplication ratio between the engine and the driven wheels, with the ring and pinion gear set inside the differential carrier providing the final stage of ratio reduction that translates transmission output into the torque and speed delivered to the axle shafts. Changing the final drive ratio is one of the most effective ways to tailor a vehicle's character for a specific purpose, with numerically higher ratios improving acceleration and towing torque at the cost of higher RPM at cruising speeds, while numerically lower ratios reduce cruise RPM and improve fuel economy at the cost of off-the-line acceleration. Performance builders choose gear ratios based on the engine's power band, the transmission's gear spacing, tire diameter, and the primary intended use whether that is drag racing, road course, towing, or overland travel. This collection covers ring and pinion gear sets for domestic trucks, muscle cars, and import performance applicati...
