Part # check ARB locker and Detroit true trac

[mk_v]

I’m getting my re gear done and my mechanic said to check out 4wheel parts because they are cheaper than what he can buy.

Right now 4 wheel parts has the arb lockers on sale.
For the rear ARB locker 8.25 with 29 spline, RD93

And Eaton Detroit true trac up front
Part number: 912A585, Dana 30 27 spline 3.73 and up

Could anyone confirm those are the right parts?

The rear axle is easy, and that ARB part number looks good to me. There's no carrier breaks on the corp 8.25 axles, and for ours (Liberty owners) you want ones that are compatible with 29 spline axle shafts. Jeep switched from 27 to 29 spline axles somewhere in the middle of the '96 model year for Cherokees. One of the kids had one of those, and it was a constant crap shoot what part would fit on her Jeep.

Front is more dicey, but according to Eaton's application guide (http://www.eaton.com/ecm/groups/public/@pub/@eaton/@per/documents/content/ct_128302.pdf) that's the correct part for 3.73 & up gearing.

Nice locker combination there, have fun with it!

Thanks for the reply. I held off buying the DTT till I could confirm that was the right part for the front. I wasnt totally confident with the guide that Eaton had. The arb was on sale for a good deal so I picked that up.
Thank you.


If anyone knows the right part number for the DTT in front, I’d like to know.

Congratulations on the upgrade. You're gonna love what she can do with that extra traction.

I don't have first hand experience with installing the Truetrac in the D30A, but there's never been more than one part number for the 3.73+ version and there's several folks who've installed or had one installed.
