I have a 2008 Jeep JK Rubicon with a 30 spline Dana 44 front axle. Will this fit my front axle, or is it only for non-Rubi 30 spline rear axles?

Asked by alain from az on

Hello Your Rubicon takes metric bearings which won't fit this E-Locker. You would have to buy a Dana locker which we carry or switch over to a different unit. Ox locker, Auburn Ected, ARB Air Locker Thanks
