The Yukon high-performance ring-and-pinion gear set for Toyota 8-inch reverse-rotation front axles delivers a 4.30 ratio with 29-spline compatibility. Yukon describes advanced heat-treating, high-grade steel and a precision tooth surface finish to reduce friction and heat; the package includes a 29-spline conversion yoke and small parts, fits earlier applications with stock 27-spline setups, and notes it does not fit clamshell designs.
