Need Help Centered rear axle

[73-cruiser]

I'm looking for people's opinion on the best centered rear axle (I preferred hi-pinion)? I need around 58" wide. I also need 4.88 gears so the TrueHi9 is not an option.

My first choice was the 14 bolt but I don't want two different rim bolting patters and I have way to much money invested in my front diff to consider changing that.

Hi All:

If you are only running 37 inch tires have a custom Toyota centered rearend built, using the Land Cruiser 9.75 inch diff and mini-truck 30 spline axle shafts. Of course you will want to truss the axle housing and use Poly Performance axle shafts.

For the GM 14 bolt, I believe that there are adapter wheel spacers available that convert that axle from 8 lug to 6 lug.

Good luck!

Alan is correct on both counts, and I agree on the ordering of the choices as well. I'm not sure if Profitts offers that modified housing, but it wouldn't surprise me if they did.

P.S. As dieselcruiserhead can confirm, it would also be a good idea to weld a sleeve over the axle housing where the spring perches go if you decide to go the Toyota route.

14bolt is cheap and 10x stronger than any Toyota centered axle. Don't give up on that thought.

If you use a C&C axle out of a cab and chassis dually truck, it's 63 inches wide. If you use 4 inch back spaced wheels from, 4wp, it only ends up an inch or two wider than a Land Cruiser axle.

14 bolt on 37's is way overkill and at least in my opinion it's going to hang down too far even shaved for only 37s. Centering a cruiser diff is easy if you go that route (having done it I can attest that it's not tough at all) and I like being able to swap thirds if I need to. Proffitts offers the housing with shafts for I believe 400. You can do it yourself for probably 100, I have 75 in mine with a pre 84 housing and post 84 shafts. If you do it that way you'll come right in at 58".

Both axles are great when they're done right so you can't really go wrong.

Some chevy trucks were built with 10 bolt and 14 bolt rear ends but had the six lug pattern. They used them in straight six four speed packages. Good luck finding them though; most have made it to the boneyard already.

Hi All:

Probably referring to the GM semi-floater "12 bolt" and "14 bolt" rearends. Yes, GM did have a semi-floater version of the 14 bolt axle.

Thanks for the suggestions looks like I will be going the Profitts route. I like the idea of sticking with toyota.

I used the piece I cut off the long side, & slipped it over ther p/u tube b4 welding in place. FYI, My U bolt plates are flipped so the sleeves needed to be wider than the perch location because the U bolt plate is wider than the perch.
