I snagged a set of AllPro springs off craigslist for $300. They are 4inch springs and the fronts are the 3 leave version. I was just wondering if anyone has any experience with these. Best way to mount them? What to do? What not to? I would like move my axle forward. I'm putting them on an 85 4Runner. Do I need the spring hanger kit from allpro to mount them or with the factory hangers am I kosher? Any info would be helpful!!
