Yukon Gear & Axle 4.88 Ratio High-Performance Ring & Pinion Kit with 29-Spline Conversion Yoke for Toyota 8" V6 Differential (YG TV6-488K)
Upgrade your older Toyota differential setup to modern heavy-duty strength while restoring off-road crawling power and throttle response with the Yukon Gear & Axle High-Performance Ring & Pinion Conversion Kit (YG TV6-488K). Precision-engineered for Toyota 8-inch 4-pinion / V6 rear differential assemblies (including factory e-locker models), this complete kit includes an upgraded 29-spline 4.88 gear set along with a matching 29-spline companion yoke, pinion seal, and pinion nut—providing a seamless conversion from factory 27-spline pinion shafts.
Manufactured from high-grade, premium steel forgings, Yukon ring and pinions undergo rigorous heat-treating and feature advanced tooth surface finishes designed to drastically reduce friction, operating temperatures, and gear noise. By converting to a 29-spline pinion stem, the YG TV6-488K delivers superior shear resistance, fatigue strength, and driveline durability for 1985-2009 4Runner, 2007-2009 FJ Cruiser, 2016-2017 Tacoma, and 2003-2009 Lexus GX470 models running 33-inch to 35-inch tires.
