86 4runner 38s auto tranny?
Ok guys I'm in the middle of a solid axle swap and I was wondering if I'm crazy to want to run 38s? I have an 86 4runner with 22re and autotranny, is this going to work? With 5.29s or 5.71s will it be ok? I already have the tires, took them off an old cj I have and I'd like to use em? What do y'all think? I do want to eventually do a manual transmission swap but for now I have the auto. It is my DD but I also want to wheel it I'm willing to sacrifice some on road performance.

 

yeah with 5.29's you will turn them fine.

 

It has to be 571 with that big a tire. The auto will smooth the power flow to the gears and they should last a long time.

 

Ok well sounds like it will work then. Looks like the saw zaw with get a work out soon to make the 38s fit. Would the 5.71s be better for wheelin? Like I said it's my DD but gotta beable to get dirty.

 

Oh and where do y'all think would be the best place to purchase them?

 

4wheelparts G2 brand. cheap and make by YUKON
lifetime warranty and offer 5.71

which you should definitely go with if you have an auto.
I wouldnt even consider anything higher. 5.71, or lower if you could find em lol

 

Link to get US GEAR....

I have been pleased with G2.....Nitro was good too. But, if it were my rig, I would go with the US GEAR. US GEAR changed the way they cut the gears(sourced the gears from a different place?) and they are the best I have seen so far. I set up a 571 US GEAR for a local guy and he has been beating the hell out of them with 38~40 inch tires. He has a 5 speed manual so that means they are taking a bad beating. They won't break.
By the way, I have 1 US GEAR 571...new.....professionally cryo treated(not heat treated)...cryo treated from this local operation http://www.cryogenicsinternational.com that you can talk me out of for 200 plus shipping of about 20 in the 48 states. It's a short pinion head 8".....sometimes called a 4 cylinder set. Same strength as the so-called V6 but cheaper in price. Most of my gear installs are of the 4 cyl pinion head type also. http://gearinstalls.com









It's not a US GEAR unless it has the "USA" and the emblem after it like this one.
