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.\u003c\/p\u003e\u003cp\u003eAt 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.\u003c\/p\u003e\u003cp\u003eBecause 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.\u003c\/p\u003e\u003cmeta name=\"description\" content=\"Upgrade your Ford with the Yukon YG F8.8-308 3.08 Ring \u0026amp; Pinion.
