ar design - Differential Install Tool

Features:

* Available in a powdercoated black finish, and in stainless steel.
* Features two 1/2" holes so you can properly torque the differential nut.
* Precision cut from 1/4" thick plate steel for strength.
* Thin enough to avoid any damage to differential seals - something common when using a ground down wrench etc.


Nice little tool for DIY differential installs at home, without the ridiculously expensive BMW tool.
