Hey guys I'm sure this has been asked before but I couldn't find an old thread on it.. So I wanting to upgrade my rear axle to 4.10 from 3.73's I have a z85 with the non locker rear end and I was wondering if this would be the gear set that I would need. GM > GM 8.0 > R&P > AAM 40001438

I am pretty sure just changing the gears won't get you a locker. You will need a locking differential along with the new gears if you want to have a locker. Also if you are 4wd you will need gears for the front too.

Yeah sorry if my post was a little confusing I'm just wondering if those would be the gears I would need for a non g80 axle. although it would be awesome to get a locker that easy And i'm only 2wd.

G80 or not the gears are for the axle housing. Not what style of carrier you have like dana 44s ect. Carriers are all the same on ours. I'd get a tru trac for the rear since your pulling it apart.

 

[Brad_IRL]

What is tru trac?

 

[gway]

It's a gear posi. No clutches. That's what I'm running.

What is tru trac?

Its a type of limited slip differential, should help eliminate the "one-tire-fire" that open diff have

I'm selling my set of 4.10s with the locker and carrier

If you weren't on the other side of the country I'd be interested. I imagine shipping would be ALOT.

Shipping on just gears and locker wouldn't be too much.

I just changed to 410 gear at the start of the year and I will give you a word of advice. It is cheaper and easier to change the whole axle and front diff to ones that already have the gears and locker in it. I got both my front diff with 410s and whole rear axle with 410s for $1000 and that includes shipping to my house. Just my two cents.

 

[BADLANDER]

I could includude the shipping costs

It depends on if you can do the work yourself of not.

4.10s and the trutrac was the best upgrade I have done so far. Do it!

I agree, you could save money by just getting an axle with 4.10s.

You have a snowballs chance in Miami to find a 4.10 rear axle with a tru trac.

 

[BADLANDER]

Nevermind the difference in the axle widths

 

[pittman]

Nope, definitely not going to find an axle with a trutrac. Though me might be able to find 4.10s with a locker, but I don't think that ever got offered in the shorter axle width so a re-gear and locker upgrade might be the only option.
