i'm going to purchase a set of lifted 52's for the front of my rig, and i can get a decent deal on a set of the pro comp springs. Now my question is that summit lists the spring rate at 280lbs/in., and i was wondering if that was enough for up front? I think tuff country springs are 295lbs/in. but i'm wondering what you guys think about running these up front? I have a small block, and no winch yet, but do plan on putting one between the frame rails sometime soon.
