Anyone know the answers to the questions they ask?

 

[McRat]

I can find the answers this weekend. I just "buried" the springs under a bunch of other stuff.

1. for the dimensions there asking I would think you would want to use a string to measure.

2. Prolly gonna need a set of scales to get the weights correct, I dont see how they can "guess" at that part, also on the rates. lol.

That would be great

Info could be in here. Warning it's a 33 MB *.pdf
Here's where I got it from. GM Upfitter

Looks pretty straight forward measuring to me Simon. Like Mike said, use a piece of string.

 

[sweetdiesel]

Dumb question but how do I measure B & C?
Is that to where the axle and leafs meet?
And (C) is that with tires on or off the ground?

 

[Bluemax]

My thoughts would be that B&C are the point where the next leaf will make contact, so it would be different from model to model maybe? And I'd guess all the measurements would be with the springs off.:dontknow:

My thoughts would be that B&C are the point where the next leaf will make contact, OK ill just measure everything and I should be good

so it would be different from model to model maybe? And I'd guess all the measurements would be with the springs off.:dontknow:

Would I be able to just have a the truck on jackstands and measure them?
with the jacstands on the frame with wheels off the ground?

Do your shocks limit your suspension drop?

I'm not sure how accurate it would be that way. It could stop when the shocks bottom out like LBZrcks is saying, or the extra weight will pull the springs and arch them a lot further than they would without any tension on them. Mike and I figured out how heavy one of these G80 axles are one day and it was insane. It was way more than my ass wanted, and we just picked it up to set it on a bar out of the receiver of an envoy. So I can tell you it'd be plenty to pull the springs down a few inches further than you'd want for accurate measurements.
