trailing arms vs leaf springs

[424shee]

I have a 70 gmc and awhile back I bought a trailing arm setup out of a longbox.I plan on putting airbags on this truck and after reading another post I'm wondering if I screwed up by buying these.will the trailing arms off a longbed work or are they longer than the shortbox ones.also would I be better off using the leafspring setup?what's the pros and cons?thanks

The trailing arms are the same regardless of whether it was a long bed or shortbed

Did you just get the truck arms or did you get the rest of the brackets, etc., from the other truck frame? It's going to be a lot of work to change over.

As for which is better - leafs or coils - it depends on your intended use. For heavy laods in the bed, the leafs would be better, IMHO. Now, I've had 2 and 1/2 rick of wet hickory firewood in the back of my '72 w/ the heavy duty coils, but I didn't have hardly any spring left. I wouldn't recommend it.

You'll be able to drop it lower and easier with the trailing arm/coil spring set up. I am going that route with my 72 GMC longbed.
