Good afternoon, gentlemen!

I was thinking of finally making the plunge into full on beast mode with my H3 and was wondering if any of you upstanding individuals have any info on the best/most stable way I would get push-button front lockers on my 2006 H3 with the 3.5 I5 engine. I have rear lockers and am extremely happy with what I can do with it. Front lockers are next on my wish-list. I do not want to modify the stock layout TOO much. Open to ideas or suggestions. I'm still a novice in the world of the H3 and any advice would be great!

Thank you in advance

 

1st, it's a locker. Lockers refers to more than one locking differential. Example: you have a rear locker.

Start with a Cast Iron front differential. No common sense in putting a locker in an aluminum front diff.

Sources for Cast Iron front diffs
Most plentiful: H3 08-10 Alpha and H3T 09-10 Alpha regardless of the packages, add a locker (will need to be re-geared to 4:56 even if it comes with a locker ex.09-10 OffRoad Package) then it's plug and play except for wiring the locker to a switch or "button" as you call it inside the cabin.
Easiest if you can find one: 09-10 Adventure (I5). This will already have a locker and 4:56 gears. Plug and play except for wiring the locker to a switch or "button" as you call it inside the cabin.

 

Hey, thanks for the quick advice! I will explore that route. It sounds like the best and easiest route to take.

 

so, air locker options are probably not the best for this thing, huh?

 

ARB locker will work also in the Cast Iron front diff.
I would not suggest ANY locker install in the Aluminum front diff.

 

Thanks again for the reply! I hate to ask a lot of questions. But would you happen to know if buying a heavy duty front Diff cover could be a way around buying a new cast iron front diff?

Or, I could just get all the parts I need from here https://www.gmpartsdirect.com/auto-p...ferential-scat

I'm having trouble checking to see if the locker comes with some of these parts or if I need to get that separately.

 

A diff cover will do nothing to beef up the diff itself.

The aluminum differential will have deflection between the pinion gear and the ring gear when enough stress/torque is applied.
No differential cover I have ever seen for the aluminum AAM7.6 will stop that.

 

I'm pretty sure I know what I should be getting from this list. But can someone go through and let me know? I don't want to miss anything.

Or should I just be searching junk yards?
