i like the wide stance of full width's and got a free 10 bolt (67")for my sas, but my rear axle is 58". obviously my rear axle is free, has 4.56's, and is locked. would like to keep it so i don't have to fork out $ for a full width. any way to make the rear axle close to the same width as the front?

go ahead and let me have it....including the ridicule for the 10 blt and this question.
 
wheel spacers & different offset rims between front & rear

what is the rear??

alot of $$$$$ to have the tubes pulled from the housing new ones pressed in & custom shafts
 
i have heard good and bad about wheel spacers, and they can be expensive. i got some of GubNi's 38 x 11 tires, not a whole lot of backspacing to work w/. it's an isuzu 12 blt rear came stock w/ the 4.56, disc, and i welded in my "locker"
 
Ive got spacers on the rear of my k5 and ive beat on it hard in the few mouths ive had it. you can get a set from allpro-offroad for about &75 plus shipping :driver::beer:
 
I do not know enough about the isuzu axle to comment any further
 
probably be alot cheaper to cut down the 10 bolt. but then your going to run into the added expense of custom axle shafts.

trust me that 'free' 10 bolt won't end up saving you any money in the long run.
 
how about a scout 44?

If you want them to match, you can run a scout D44 front. It's about 58". Those can be had for ~$150 hub to hub, but then you'd need gears.

Of course, you won't get the full width.

Stupid ? are the internals the same as a GM 12 bolt?
 
How about Wider rims or change backspacing ?? Used Wheels are cheap

:popcorn:
 
if this isnt gonna be a daily driver i would sell both of those axles and get whatever 3/4 ton setup will fix you up. i dont know if you are driver drop or passy drop, but running those 38's you should at least get a rear axle to handle those. like a d60 or 14bolt and a dana 44 up front. either being found under an f250 or chevy 2500 of whatever year. better for you in the long run than a 12bolt or 10 bolt will ever be. total waste of money to retube such a shitty axle and thats either one of those.
 
shitty axle? you know not of what you speak.:flipoff2:

the isuzu 12 bolt is a damn good axle. it'll hold up to 38's no problem.

that said, you're going to put alot of time and effort into widening it. you'd be much better off just buying something else.

fwiw, there are wider versions of the isuzu 12 bolt. 63" wms-wms is the widest iirc.

just get some spacers/adapters. they'll get you close enough. alot of people purposely run a narrower rear anyway.

Front Dana 44 is almost identical to a 10 bolt.
If anything the 10b is marginally stronger.
The 10b will hold up fine to 38s and a light right foot.

Mine has survived in my k5 on 42s and now 38.5s for 4 years.

Of course I know what it is. And treat it as such.Plus I can keep a dozen complete spare 8 lug 10bolts for the cost of 1 D60.

As to the question. It aint gonna be cheap to stretch the isuzu axle. You will probably be able to buy and build a 14 bolt for half the cost of stretchig the special 12.

BTW that 12 is a hella axle. Id bet you could sell the Zoo axle and pay for a 14.
 
thanks for all the ideas. with all the above information i'll probably just get some spacers and maybe some wheels (if i come across some cheap ones) and wheel it till it breaks.

unless someone out there wants to trade my rear for a 14blt.

x2. 10 bolts have thicker gearsets, iirc.
 
how about you chill for a week or 2 and im sure somthing will pop up for sale that will work perfectly..

I thought i saw a chevy 12bolt a week or so ago.. NUSS????? where are you??

Stuffs out there just get your game plan and just seek it out..
 
Custom back spaced wheels from Summit racing. Less than $140...no shipping charges.
Now to be honest, I don't know what it would need....Zooks and width aren't familiar w/ each other.
But, playing w/ the backspacing could get you close for cheap.

theres wayyyyyyy more aftermarket for a front dana 44, comparing the two stock is a tossup and theres way more aftermarket for a rear 60 or 14 bolt. i hammer on my shit so thats how i think, and me thinks a 12 bolt isuzu wouldnt last long. sell the 12 bolt to a samurai guy or something. you can get a 60 rear for 100-150 if you just look in the right places.

it'll hold up fine. a 30 spline d60 isn't really an upgrade from an isuzu 12 bolt in terms of strength. if he's going to spend the money on something else, he might as well go for a 14 bolt or d70.
 
Back when I first did the SAS on my trooper I had a chevy fullwidth dana 44 in the front and a isuzu 12 bolt in the back. I bought a set of 3" toyota wheel spacers from marlin and called it done. I never had any problem with them. I was running 38s and a V8 at the time with the rear welded.
