My s10 is due for both ball joint replacements, but I'm looking into putting about a 2.5 inch life on it. So, I'm wondering if I should replace the ball joints before the lift, or will the lift come with a new set? I don't really know anything about suspension, so any advise would be greatly appreciated.

 

do you need both uppers and lowers? rough country's kit for 4wd comes with uppers
