Pinion nut for early model Dana 25, 27, 30, 44, and 50. It also fits Dana transfer cases 18, 20, 300.
Warning: Most axles that this nut fits use a crush sleeve to preload the pinion bearing. Improper installation of this part can cause catastrophic failure. If you don't know what that is, or aren't sure if you have a crush sleeve, give us a call or consult with local installer.
