Probably but I STRONGLY (!!!) suggest you not buy the gears, locker, etc. on your own trying to save a few bucks with the intention of giving the parts to the installing shop. Have the shop provide all parts. Period. It may cost a tad more but then the installing shop's warranty will cover everything, all parts and labor, instead of just their labor.
If you think the gear and locker manufacturer provides a warranty that's true BUT if something fails, the usual cause of the failure of gears and/or lockers is due to the installer screwing something up. And if that happens, the installing shop will blame the parts you provided and claim they installed everything perfectly. The gear/locker dealer will blame the installation process, which is indeed the usual source of post-installation problems.
By having the shop provide everything they can't point their fingers at anyone but themselves. You can tell them you want an ARB locker and Revolution Gear gears but have them source them themselves. That can eliminate a whole lot of grief, problems, and finger-pointing.
