14 Bolt Axle

The Corporate 14 Bolt Axle is one of the most commonly used "one ton" axles utilized when building a custom rock crawler or rock bouncer.  The Corp 14 Bolt is often referred to simply as a "14 Bolt" because of the 14 bolts used in the diff cover.  Keep in mind there are some other differential housings out there that also use 14 bolts so you need to pay attention when identifying a Corp 14 Bolt Axle Housing. To Make this even more difficult the 14 Bolt Axle is offered in both a semi float and full float version.  The full float Corp 14 Bolt Axle is the one most commonly used because of the pinion support and full floating axles.
