I've given up on researching this and have decided just to ask; anyone know of an aftermarket locker for the H3T? Do the H3 applications cross over (do we share the same drivechain components). And for future reference, where can I find info like this for myself??

 

Arb (air) or Eaton (electric and is what GM used for its OEM lockers).

H3s and H3Ts have the same suspension and drive train (except for the rear drive shaft is longer for the T).

Search forums and google .... etc.

 

excellent...thanks.

 

I was looking at the Eaton but it looks like it only comes in the 2.75 for the H3, I have the Alpha with the 3.1 gears.. I am assuming adding the 2.75 is not a good idea

 

Ummm Ahhhhh Ummmmm, What you talkin' bout Willis?

I5s have 4:56 gears and V8s have 4:10 gears plus Eaton makes the OEM lockers for both the I5s and V8s in the Adventure/OffRoad packages in 2009 and 2010 H3/H3Ts.

All V8s will also have the Cast Iron front diff (08/09/10), Only the Adventure/OffRoad I5s will have the Cast Iron front diff (09/10). The rest of the I5s will have the Alum. front diff. I would not recomend puting a front locker in an Alum. front diff. They have case deflection (twisting internally) issues that cause blown ring gears, sheared teeth on the pinion gear and broken shafts.

 

Yeah bit of a brain fart there

 

Willis here. Like I said the 3 and 3T are the same. You still have to compare apples to apples (alpha to alpha and I5 to I5) Doh.

 

The OEM lockers in any Alpha are Eatons, so yes you can buy an Eaton on ebay for your Alpha.
