Hello all,


New here and new to SAS in general so be nice. Well I am looking at getting a GM 383 Stroker from Smeding Performance with 330 horse and 430 ft pounds of torque, 400 of which is available from 2000 to 5000 rpm. I am trying to keep up with a friend in an old Ford with a built 460 sitting on 36" swampers and 5" highrise lift springs.

I am pretty sure that the engine I will be putting in is going to cause some serious havoc on my rear end. My 4runner already has a 4" lift 1" body and some work done to the IFS. I am thinking that I want to get solid axle for off road purposes, looks fun to do, and looks real cool. Also I live in the Northwest all wheels on the ground is the key.

I am looking for suggestions for solid axles. I have been reading here and other sites about the SAS and just want to make sure that I get the right stuff. I can get DANA 44s or 60s on CL for about 250 each, probably more like 400 of 500 with disk breaks. I think that the engine may be too much for TOY axles???

I have a buddy that has been a welder for 10 years and im a machinist, and have been for 3 years

Thank in advance.

If your'e gonna be puttin that much power in your truck id definately go with Dana 60s. Also the trans should go to. Maybe a TH400 and NP205, somethin thats meant for a 1 ton and not a little yota.

Oh and if you can get a Dana60 front for $250 send a few of them my way!

Dana 60s eh? Thats what I thought. So do you think that the engine might be overkill? I have a old 350 in there now, its blowing oil past the rings, so I thought that I would replace it. I am going with a 383 because I have always wanted one and since I just sold my 1970 Chevy Nova I have the money and I wanted to do a little more for the yota since I sold the car.

It already has a turbo 350 tranny with a shift kit i'll probably just run it till I kill it then upgrade.

Would a Dana 44 work for the front or should i just go 60s all the way around?

WFO

I wouldnt say the engine would be overkill, but I wouldnt say that about any engine! haha
Dana 44s would work fine, but its probably not much of an upgrade from your IFS, except for the flex.

I really depends on what youre gonna do with it. If youre gonna wheel it hard the 44s probably wont hold up too well. If its gonna be a mall crawler you should be fine.

Think about how youre gonna use it, price out both axles (complete, under the truck) and go from there, the 60s are gonna be much more expensive, at least the front, but if youre not gonna use it that hard it wouldnt be worth the extra expense. And if you are gonna use it that hard you dont want to end up building a 44 and then in the near future building a 60.

The toy rear is roughly the same strength as a 60. The ringear is weaker and thats where you will run into problems. You can get longs for the front and be up to snuff on Dana 60 parts but again the ring gear is a weak link.

I like your style.

Its just that I found this for cheaper than I could build it

"This is the perfect axle to swap in the front of a toyota pickup or 4 Runner. This axle was originally out of an F-250 then it had the tubes swapped and narrowed. It is passanger drop with a wms of ~61". It has 5.38 gears and an ARB locker, Warn alloy shafts, warn premium hubs, and spicer u-joints. The axle uses disk brakes off of a J20 jeep. It is 6 lug. The axle uses custom made High steer arms that are 1"thick. The tie rod and drag link are dom with heim joints. The tie rod will need to be replaced as it has a slight bend."


And was wondering if it would hold up in the front, I am going with a Dana 60 in the back for sure. As for the wheelin part I'm fairly new, but I'm a person that would rather buy once than twice, if you know what I mean. I am going with Danas for the flex and the strength. What kinda wheelin would reqiure the Dana 60?

Do you think that I should go with "full width" or a "narrowed". Some people cut them down on the long side to fit the Toyota WMS to WMS and some people just buy the Standard width kit and mount them standard size. What would you suggest? I also thought that a wider stance was better?

Thanks for you advice, this is all new to me just learning as I read.

So the little Toyota rear end is as strong as a Dana 60?? I thought that I was going to have to upgrade to a stronger rear end for the 383. Can you get a stronger ring gear to put in? I thought about going with the longs, because it would probably be cheaper, but I have read here that if your going with a gm 350 or anything bigger that you can break the longs pretty easily. I have read that Dana 60 are the way to go, but like I said this is all new to me. I just paid mu 4 runner off and now I can modify it to my pleasing so I am learning as I go.

Any suggestions are always helpful.

Just a list of axle strengths tested by Bobby Long. The only weak point after longs (4240 chromos) is the ring gear. If you must go even stonger you can get 60's and get chromo shafts and be pretty well setup. After that its Rockwells and Unimogs.

And the ring gear cant be any stronger. Staing with a 4.10 will help but to get more srength you need a larger Dia. Ring gear.

Thanks for the info Alpine.

I think I understand what you mean. The axles are almost as strong, but the gear inside the housing is smaller so it is more likely to break.

I found some Dana 60s, on the list, full floating, disk brakes, narrowed to 66" wms to wms, with 32 spline inner and outers, rebuilt for about 2000 for the pair. Oh yeh and the spring perches are 27.5" in between and with 8 lug.

What do you think? Good price? Just need to gear em, lock em, and put new tires on of course?

Is the 32 spline inner and outers ok? I have heard that you want 35 inner and 30 outer.

I'm not a buff on Dana axles. Search pirate, i see you have been post flamed already Lots of info on there regarding this, its just finding it.

What year Dana axles? What are they off of.
