Want 4:10 gears... Options?

I have been searching for a couple days and I am still a little lost.
I am getting 255/85/16's really soon and from what I've learned so far, a re-gear may be in order.

My truck is a 2006 4X4 double cab, so it is a 4.0L, it is an automatic, and it does have the optional mechLSD in the rear.

If I drive it and it seems even the least bit gimpy with the 33's on there, it will get re-geared.

What are my options if I just want to go to 4:10's? Specifically, can I just do a front and rear 3rd swap with an OG Toyota unit?

I would like to at least keep the mechLSD in the back, (maybe step it up to a locker but that is not the goal here.)
The goal is to get back to stock gearing. I will never run 35's and I don't get too crawlery, so I don't want 4:56's.

My question is simple I hope, what year and model trucks are compatible with mine...
Tundra? T100? 1stgen Tacoma? 2ndgen 4cyl? FJ?

Pic for click! It's got 115K miles, but it's paid for!

 

You need factory gears from a 4cyl second gen. You'll want to find em used as Toyota charges a ton for the factory 4.10's

 

I wonder if ECGs can hook you up at a reasonable price.

 

http://www.iwerearendsonly.com/ ... if you're looking for gears, these guys are the best. I dealt with them before, fantastic... but they are in Canada. Close to the border tho.

 

Try it out first.

You may decide not worth the cost and hassle.

If you decide you want 4.10s, PM me as I've got my factory take-offs from when I regeared a couple months ago, including the front carrier which you will need.

 

I thought the only 4.10's were OE?

 

Thanks.

I looked into that, seemed expensive.

I will check them out, thanks.

I looked into that already, if, I was going with 4:56's I would have already ordered them from the GB. Since I just want 4:10's I think just swapping OEM Toyota parts makes more sense.

Yeah, I am going to check it out first. I have 285's now and I think it does OK for the most part. The 33's are only 1" bigger so I may be OK, but if I can do a simple swap and get 4:10's... why not right?

I'll PM you!

Thanks guys, I appreciate all the input!

 

Subbed for when I get 285's.
BTW, I didn't realize the mechanical LSD was an option on the SR5's back then. Thought it was only the Sports.

 

I actually just found that out as well. There is a sticker on my rear diff that says "only LSD oil."

I lucked out I guess, I just bought the truck a couple months ago, but I am thinking it may be part of the tow/hitch package?
(Which mine has as well.)

 

Just a quick update:

I have a buddy that owns/runs a garage and mostly does Toyotas. He has done lots of re-gear jobs before.

He says he found me a 4:10 front at a local JY for $500 or so, and he has the parts to rebuild my rear on hand...

He just quoted me $1300-$1400. That includes all parts and labor, and the end result would be all OEM equipment (Toyota gears) with 4:10's in the front and rear. And, I get to keep my same mechLSD in the rear to boot!

Thoughts???

I am probably going to drop the truck off within the next few days, I don't think I am going to find a better solution/deal anywhere...

 

Do It

 

I have 285's with the 4.0 and it still moves just fine. I don't think u should need a regear with 255's. That's just my opinion.

 

Anybody else??? It's looking like I am dropping the truck off for this tomorrow...

 

4.10 front diff....

Wow, great timing... I will check it out,

Thanks man!

 

Remembered I saw that the other day and saw you were in OR. I'm going with 4.56. Where are you getting yours installed?

 

My buddy is doing it.

He has been working on Toyota's forever and has done lots of re-gears before. He has his own mechanics business/garage that he runs. It is pretty much a 1 man show, but he has a really nice shop with a lift and all that good stuff. I am no expert but $1300 out the door sounds like a great deal to me. I did send that CL guy an email though, always good to have options!

 

Try backing up with a loaded trailer with your 6 speed. You can tell.
