? from looking at the formula it doesn't seem so.
:confused: :confused:

Well yes and no. Spring rate is figured in what it take to get the spring to move the first 1". So some springs have a more progressive rate to them where others do not.

I'm in a pickele because there are 2 springs I'm looking at. Waggy lift springs from BDS and Rusty's. BDS is 450 lbs/in and Rusty's are 310 lbs/in but someone said that the BDS ones aren't too stiff. Should I get a pair of each and see what happens? :confused: I wish someone would have put them on a YJ already. I think the added wheelbase and bolt on almost 6" lift is a great idea. yes no?

So it sounds like you need to post the question "who has used Rusty or BDS waggy springs"? I seems as though most people are happy with their BDS springs.
