Leaf pack on 77 dually

[babyburb]

Does anyone know off hand what size rear leaf spring is on a 77 crew cab dually? The vehicle is not mine, I was looking for 56" springs instead of my 52" and was wanting to know before I approach the person. I MIGHT be able to get them for free if so.
Thanks

Likely to be 56"s, yes. Note that a dually will prolly have a great many leaves, so you'll need to take a few out to make them flex. My 56"s came from my crewcab originally, and went from 8 or 9 leaves to five or six.

so I would just unbolt the pack take out the top 3 or 4 and bolt them back down?

Well, obviously you need the top leaf, as it has the eyes

You can finetune it ... I think I took out every other one, or something. It's a handy way to change ride height in the back and adjust flex

Kind of a different question but would the longer leaves or shorter ones do more to stiffen up a spring?

I think the longer ones would, IF the thickness was the same. Unless the metal was treated differently for varying spring rate.

Err. That's complicated physics and my head hurts.

the longer the leaf the softer it ride look at it that way (it is easyer to flex a piece of flat steel bar that is 10ft long whit ur hand then a 4 inch piece)
keep the first 2 from the top then remove a few here and there

remember the longer,the softer the ride and remember to put back the helper too(the last one that is thiker)

just take a look a new truck they all have long leaf in there(light duty truck anyway)

keep in mind i work in a spring shop all day long...

hope it helped a bit!!

Thanks for the info so far. I'm might try to go this weekend to look at them.

Is free a good deal? I dunno, we'll find out
