4" lift springs?

[wsuweston]

I am going to look at a set of used 4" front springs that a guy localy has for sale. He does not know what brand they are and said that he had them mounted to a stock truck. Is this possible? I thought you had to extend your brake lines with a 4" lift. How do I measure them to see if they will bolt up to my stock truck? I don't mind extending my brake lines, just don't want to move spring perches and stuff.
Thanks for the help

im pretty sure that a 4" lift is right there on the edge of extending the lines! some will say to some wont! I figure if you dont want to spend money but want to play it on the safe side then you can always unbolt the brake line mounts and bend em down a bit. its kinda jerry riged and theres other ways but you no what it worked for me and i have 5" in the front and 6" in the rear. so its whatever

i ran stock brake lines for along time.. untill you flex out and they bust :grin: but bend the mount or just buy brake lines they aint to much

if they are 4 inch on a stock truck that means they are stock length springs = so probably pro crap, sky crapper, or super lift junk
