Yukon Gear & Axle YG F8.8-488-15 High Performance Ring & Pinion Set Ford 8.8" 4.88 Ratio

The Yukon Gear & Axle YG F8.8-488-15 is a high-performance ring and pinion gear set engineered specifically for 2015 and newer Ford 8.8" axle applications, including the F-150 and Mustang. Featuring a 4.88 ratio, this gear set is an excellent choice for enthusiasts and off-road builds seeking stronger acceleration and increased low-end torque.

Yukon designs each ring and pinion using high-grade steel with a precision-engineered gear tooth surface finish that reduces friction and heat buildup under demanding conditions. All fitment dimensions are manufactured to OEM specifications, ensuring a reliable, professional-grade installation.

Key Features:

• 4.88 gear ratio for increased torque multiplication and performance
• Designed for 2015 & up Ford F-150 and Mustang with the Super 8.8" axle
• High-grade steel construction with optimized tooth surface finish to minimize friction and heat
• Manufactured to OEM fitment specifications for accurate, repeatable installation
• Fits carrier cases with 3.31–3.73 ratio range and 2.400" deck height
• Important: The 2015+ Super 8.8" axle features larger pinion bearing journals and pinion splines than the pre-2015 Ford 8.8" — these components are not interchangeable
• A new carrier case is required when replacing a factory 3.15 ratio

Yukon Gear & Axle ring and pinion sets are trusted by performance builders and professionals alike for their consistent quality, precise manufacturing tolerances, and long service life. The YG F8.8-488-15 is the correct replacement or upgrade gear set for the updated Super 8.8" platform introduced on 2015+ Ford vehicles.
