Question about 133" and 157" 1 tons - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**bobvilla67** · 05-26-2005, 12:30 PM

Is there any difference in the 133" and 157" 1 tons besides the obvious length?Is there any pros or cons to either?thanks,Bobby

I think the difference would be more in the GVW rather than the WB. It also depends on what you plan to do with the vehicle.

Have fun - Bob

Depends on what you wanna do with it. Longer WB for towing, shorter WB for rigging out a welder's truck for example.

I was thinking about building a tow truck eventually, but haven't really seen too many around here to compare.Would the suspension from an 85 1 ton bolt into a 67-72 1 ton?thanks again,Bobby

Seems to me the 157 wheel base use a different style leaf pack. My 72 1 ton with 133 inch wheel base 1 ton has a 7 main and 6 leaf aux. The 157 use 8 and 1 in aux. The 157 typically have a high GVW in 1970 and up..the 133 are rarer to find the high GVW..Im taking 14000 lbs max gvw.

For a tow truck using a cradle only you'd probably like the 133 inch for the shorter conditons needed in some towing application hook ups.
With the 157 you could use it as a car hauler on a deck.

There are some differences on the size of the channel for the frames too on the higher GVW ones.

From what I've seen the 9/16 wheel stud pattern started in 1970 on some editions of these 1 tons. Might be easier to find wheels for that diameter hub.

So knowing all that ..well you can see why I grabbed up the 1 ton I have...it was exactly what I wanted..and it wasn't easy to find.

Thanks Rod for the info.I found a 68 model and a 72 model, both with 157" wb.I think I may try to buy both and see which one I like more.I also have an 85 1 ton that I was thinking of parting and using the running gear for the 68,so I would have the disc brakes.Does anyone know if it would be a direct bolt-in?Don't have the trucks here to compare.thanks again for the help guys.Bobby

Not sure..dont play with anything that new.
I got a 77 duallie myself I could carve away at but never attempted too yet. I'm pretty sure the 77 will go if I drill more holes for the saddle..but I have more of an interest of making it a 4x4 one day. I grabbed my Dana 60 front already after a couple year search for decently priced one. Just need the brackets..I thought I bought a set off the board but never heard back yet from the seller.
