This kit uses an aftermarket aluminum rear housing. The aluminum housing is not prone to wear like the OE magnesium case. A wear plate is not believed to be necessary, but included for good measure. -JK

Kit includes new aluminum case rear half, wear plate, transfer case to transmission gasket, rear output seal, and a tube of sealant for the case halves. You will need to transfer your fill and drain plugs along with speed sensor and the oblong rubber access grommet.

"This kit is for the guy who caught his leak before destroying the internals of the transfer case by running it dry. I cannot tell you if you will need to repair further if you have traveled long enough to make noise." -JK

This is the rear housing only. Tailshaft bushing and front shaft pinion support bearing installed.

"This is an aftermarket aluminum case. The aluminum case is not prone to wear like the OE case was so there is no need for a wear plate"-J.K.
