The USA Standard Gear ring and pinion set for Chrysler 10.5-inch differentials offers a 3.73 ratio, designed to exceed OEM specifications. It is suitable for rear differential applications. This ring and pinion kit is compatible with a range of Dodge and Ram trucks, including the Ram 1500 from 2006-2010, the Ram 2500 from 2003-2010, and the Ram 2500 Van in 2003. It also fits Ram 1500 and 2500 models from 2011-2013. The differential features a 10.5-inch ring gear diameter, 30 spline pinion count, and 14 differential cover bolts.
