GM rear end widths info Christmas gift request

Re: Christmas gift request


Iím working on my wife to get a new rear end for Christmas. Ok guys calm down itís for my 36 Truck!

Doing rough measurements on paper, of a selection of wheel back spacingís and body width Iím ending up needing a rear end around 66Ē from wheel mounting surfaces on axel shafts.

To keep things consistent I would like to use something from GM possibly 1988 and up and 6 lug but not floating.

I have charts showing GM made OEM non floating 6 Logs rear ends but canít find actual measurements to know what is even out there to work with.

To save money a junkyard find that I could refurbish and upgrade later would work. I could redesign but would like to keep extra body work down if I can.

So does anyone have information or know of a web site with GM rear end widths info?

Happy thanksgiving to all

And have a Christmas you will never forget Öand a new yearís party you find hard to remember.

Mike

I would look into 88-98 4wd 1/2 ton Chevy/Gmc trucks, they are going to be the closest to what your looking for. 3/4 ton and up most likely will have the full floating rear end. Maybe slightly narrower, maybe an inch.

RE: GM rear end widths info Christmas gift request

To keep things consistent I would like to use something from GM possibly 1988 and up and 6 lug but not floating.

But the rear end needs to stand up to a mild 350 LS1

(Around 66Ē to 64" from wheel mounting surfaces on axle shafts.)

GM: 88-2000 Pickup,1/2-ton (6 Lug)
92-98 Suburban Tahoe 4x2/4x4 (6 Lug)
99-2001 Silverado/Sierra 1/2-ton 4x2/4x4 6Lug

These are just some possibilities I found but canít find width information.

Rear end could even be from a car. I will probably relocating leaf spring anyway, its just width to consider.

most '81-up 3/4 were SF rear 9.5" actually, new axle model for this year and up


but 1 ton were 10.5" FF

most full size axles were about this width

almost any year

there are many internet pages out there with common vehicle model axle widths

google will have many results

RE: GM rear end widths info Christmas gift request

I found a lot of information on the Web, telling me the width Year make and model. Other telling me 5 or 6 Lug Year make and model.
Then others telling floating or non-floating.

But the lists I have found give me Lug of 5 or 6 for 1980 and up and other give me rear end widths in the 70s.

If I could find someone, a business or a web lest telling rear end width for 1980 and up that would be great.

I would love to call a vendor and tell them the size I need but in this economy to move forward I need the rear end to be a used one I could get rebuild.

But most places I call say it is to much trouble or tell us what you want or
never call or email me back.



Iím even willing to drive a couple of stat away if I could find a used rear end some one or junk yard would measure that was 80s and up

Its tough because I have to make sure before I buy a rear end that the brakes tires and wheels will fit. Then i have to find out if the Stainless Steal Brakes I used on the front will work with Stainless Steal Brake upgrade for the rear.
Which they probably will but I donít want to take chances, time is cheap but money is harder to come by.

Thanks again

The 2 wd and 4wd 88-98 1/2 tons are the same width, just 5 or 6 lug. Why worry about a brake upgrade on a truck rear, these brakes are designed to stop a 4000+ lb truck?

Thanks

The more information the better.

I may want to put disk brakes on the rear to match the disk on the front.
It's just an option i am keeping open. just like using a 6 Lug over a 5 Lug its an option to keep open when i rebuild the axle.

you mentioned the axle where the same on "2 wd and 4wd 88-98 1/2 tons", do you know the width on the Axles?

Thanks

Not exactly, but my 1st post I mentioned an inch narrower than what you were looking for. If I remember right about 65" from wheel surface to wheel surface.
Also some 3/4 2wd are 6 lug non floating but have some really huge drum brakes.

I don't see the point adding disc brakes, seems alot of people think drums brakes are junk, they are more than capable of stopping a vehicle. I prefer the feel of rear drum brakes myself.
