I have a 4 inch Superlift Superride on my 90 Blazer. Here is my Dilemma, I want another inch or two lift. A: do I go with a front shackle lift for an extra inch or so.. or B: buy new BDS springs. I have heard good things about them but, is there really that much difference to make it worth buying a new set of springs..? I only do about 10 % offroad. I would like aa little softer ride but, flex is not too much of a concern...What do you think I need advice.. I just did a shackle flip in the rear with two inch rear spring lift..... WHat do you guys think.. there is a major difference in price like $200..my labor is no concern...
