This is perfect for small shops and will allow you to build your own custom width rear end easily. Axle length is measured from the flange to the end of the splines.  All CTF axles come with a full installation package which includes one set of five 1/2"-20 Ford style wheel studs, one set of five 7/16"-20 Chevy style wheel studs, one set-20 tapered roller bearing with race, seal, & collar, and one heavy duty late model large bearing style retainer plate.
