The Yukon 8.25-inch IFS reverse-rotation GM ring-and-pinion in a 4.56 ratio is a direct-fit replacement for 2013-and-earlier GM 8.25in IFS reverse-rotation applications. Yukon relies on precision tooth finishing, advanced heat-treating and high-grade steel to reduce friction and heat while meeting OEM fit. The kit includes an 8.25" ring, a 30-spline pinion and ten ring bolts, and is covered by Yukon’s Y.E.S. lifetime protection plan.
