This combination from Yukon Gear and Axle upgrades your current 30 spline to MASSIVE 38 spline axle shafts for your 2003 to 2012 Dodge with AAM 11.5" rear differential. This project requires you to upgrade the carrier to 38 spline Yukon Grizzly Locker on top of the axle. It will not work without the larger carrier.

Installation
Yukon's 38 spline axles are larger diameter than stock, 1.625" in diameter to 1.550" diameter stock shafts. This upgrade requires boaring of spindles and a new 38 spline differential is needed to upgrade axles. This is not a bolt on kit. Please have a professional mechanic install it if you do not know what you are doing.
