hey all, newbie lookin for advice on which 4" kit to buy for my 74 blazer. im goin with either tuff country HD or skyjacker. main concerns are ride height and flex. i know the TC springs are super flexy, but i dont plan on doing anything really extreme.the spring rates for these 2 companies show that skyjacker has a higher free arch than TC by about 3/4", and has a higher spring rate. any and all comments are appreciated!
