Yukon 1541H alloy rear axle shaft for 1988-2000 GM 2WD trucks with an 8.5-inch rear end. It has 30 splines and a five-lug wheel flange.
 
The shaft carries drive from the differential to the rear wheel. Yukon uses alloy construction and heat treatment for greater strength than the stock axle, making this a replacement for a worn or damaged factory shaft.
