Anybody try the rear lift with Express 2500 leafs? Having a hard time justifying pulling old 1999 springs from the Suburban 2500 and putting them on a 2013. My local junkyard has a bunch of 2500s though that would have good springs and good bushings
Springs are something I wouldn't waste my time with scrounging up used. When you buy new you know exactly what you are getting.
I bought mine from general spring. Actually I believe I have bought several pairs of leave springs from them over the years.
Edit to add
I just checked the spring dimensions and it looks like the suburban springs and express springs are the same length and width. Springs are springs and it doesn't matter what application they are tagged for as long as the dimensions and spring rate are correct. You would just need to do the homework and make sure everything jives
The "Suburban" springs some of us have used are 2900# 6 leaf and 3 7/16" thick
Listed on the general spring website for the Express are also 4,5,9 and 10 leaf springs with the heaviest being 4600# so be aware that while "Express" springs from a donor will probably fit they may not be what you are looking for without knowing the spring rate.
