Dual Wheel Conversion

[ponjohn]

I asked this question in a previous post about the 14 bolt gear ratio. I thought it required a new thread.

What rear would be required to perform this conversion with the result being factory appearing? Meaning I want to use the rear fenders. Does andybody have a width measurement BP to BP for the correct rear?

ponjohn,

I think any 1 ton dually parts from 73-91 should bolt on. I've seen a 87-91 blazer converted to a dually rear!!! It was for sale. If I see it again I'll take a picture of it. If the dually will bolt to a Blazer the rear ends should bolt to a truck. The easiest conversion is to find a dually bed. The fenders are availble but you would have to put them on yourself.

That would be great. I have seen suburbans converted to, ends up being a nice package. You say the fenders are still available, is the from GM?

I beleive the pickup rear is wider than the cab/chassis?

Thanks,
john

I do not know all the #'s But I know that there are at least 3 different 14 bolt rears
single wheel
cab & chassis
dual wheel pickup
I also believe the spring hangers are different and the shock mounts are as well

i have a 1976 3/4 ton crew cab that i converted to one ton dually by using Arrow Craft wheel adapters on the rear, and i changed the spindle, rotor and calipers on the front. The ball joint sizes are the same for a 3/4 and one ton front ends and so are the upper and lower control arms. I sent one day doing the front end and about two hours on the rear. I bought some dually fenders from an afermarket fiberglass company, but the fendes are not the same as gm fenders (they mount differently, but look the same). So i found a dually bed and put it on my truck.

prices for the adapters were 449.50 shipping included. I bought them through T.E.A. 1-800-500-0497, or 1-713-644-0497

i bought the bed for 600.00 and spent about 400.00 on the parts for the front end, that includes the parts for new bushings and ball joints from Auto Zone.

Hope this helps

later
