I am going to look at a set of '4" lift springs' today and wanted to find out how to tell if they are what he is saying they are. What measurements should I make? How is length measured? What is stock length for 1st gens?
He said that he ran them with everything stock (driveline, brake lines ect.) is this possible, I thought you had to extend the brakelines for 4". Also how do you tell if they are worn out?
Thanks for the help.

 

I run 3.5 lift springs with stock lines. Look for cracks in the springs, and make shure the springs match. Make shure one is not more flat than the other. Generally speaking its hard to mess up leaf springs.
