I think this is what you want: http://www.stovebolt.com/techtips/2-speed%20axle.htm

Have a service manual yet?
It will answer most of your "I've got a new truck, now what?" questions.

let me clear up my line of inquires about my truck: throwing a little caution to the wind seems to be a good thing in my book and by that i mean rushing into something you have little or no knowledge about usually costs you money, at least it does me. last thing i wan't to do i have to spend extra bucks and hours fixing something that a simple question would have prevented. manuals are great and also at times can be vague at best. is their a recomended manual i need to purchase? like i said in one of my first posts "i'm new to the big trucks"

10 micron,

Check out the part numbers on this link - the Master Parts Catalog.

Post the part numbers here and I will compare the Chevrolet part numbers to GMC part numbers for the same year (I have bought those brake parts for my 54/55 GMC 2-ton COE).

I fully understand your question and your comment about being careful and being new to big trucks (a new world for us small truck people). Part numbers are not usually in a Shop Manual. Nonetheless, a Shop Manual will tell you what sizes of trucks have matching brake systems/parts (but not give part numbers).

I was very fortunate to be given GMC part numbers for my truck by big-truck people on the oldGMCtruck.com website.

Good luck,
Tim

You will find that most all of your questions can be answered here. Just at times you will need a combination of the info in the service manual, and what you learn here.

That is why I still suggest you find a service manual, sold by the regular antique Chevy truck parts places. Yes, it can be vague at times, but most of the time it can be very helpful.

I have two for my truck, one to use in the shop and take on long trips in the truck, and one for in the house, often fall asleep reading it.

10 Micron,

Brakes will be the same for single and 2-speed rears.

The single speed rear has a 6.17 ratio.

2-speed ratio could be 5.83/7.95 or 6.40/8.72.

The ratio should be stamped on the right front face or top of the rear. Take a wire brush and start cleaning to see what you have.

Hope this helps.
