In the rear, we installed a Corporate 14-bolt rear axle built by ORU. We picked this axle because of its strength. We scored a Detroit Locker to simplify the search for traction. One of the nice things about the 14-bolt axle, aside from having the added support of an extra pinion bearing (see arrow), is its ability to accommodate an affordabl Detroit Locker. Due to its simplicity of design, a 14-bolt Detroit Locker typically runs under $400.
