Fitment Notes

Does not fit 2010-2014 Mustang GT500 and other big-bearing/31-spline Mustang applications - this gear set uses a 30-spline pinion and will not match the 31-spline, 3.250" OD pinion bearing setup used on those cars
The Ford 8.8" rear axle spans many spline counts, bearing sizes, and solid-axle vs. independent-rear-suspension designs across its production history; confirm your axle tag or door-jamb axle code before ordering, especially on Mustang, Explorer, and Ranger applications where multiple 8.8" variants were offered
Fits standard-rotation (non-reverse) 8.8" rear differentials only - not for use in front IFS applications

Features

High-performance ring & pinion gear set engineered to OEM fitment specifications
Advanced heat-treating process increases gear strength under high-torque conditions
Precision-finished gear tooth surface reduces friction and operating heat
High-grade steel construction on both ring and pinion for extended service life
Designed and validated through Yukon's in-house engineering and quality-testing labs
Quiet, smooth-running gear set suited for towing, daily driving, and highway cruising
Matched and lapped ring and pinion set for consistent tooth contact pattern
3.08 ratio well suited to restoring fuel economy and lowering highway RPM on stock-tire applications

Product Description

The Yukon YG F8.8-308 is a high-performance ring & pinion gear set built for the standard-rotation Ford 8.8" rear differential, one of the most widely used rear axles across Ford, Lincoln, and Mercury's truck, SUV, and full-size car lineups. Manufactured to OEM fitment tolerances and finished using Yukon's advanced heat-treating and precision gear-cutting processes, this set is engineered to run quiet under normal driving while holding up to towing, highway cruising, and daily use.

At a 3.08:1 ratio, this gear set is commonly used to restore fuel economy and lower engine RPM at highway speeds, particularly on trucks and cars running factory-size tires that want a more relaxed cruising ratio. The ring and pinion are matched and lapped as a set, and Yukon's gear tooth surface finish is designed to minimize friction and heat buildup over long-term use.

Because the Ford 8.8" axle was produced in several spline and bearing configurations over its long production run, confirming your specific axle variant before ordering is important - this set uses a 30-spline pinion and is not compatible with the 31-spline, big-bearing 8.8" differential found in select high-performance Mustang applications. It does not include an installation kit, bearings, seals, or a crush sleeve; a compatible install kit is required to complete the swap.
