No I would go with a heavier aftermarket spring and lose the longer shackle. But your talking to someone who has 3/4 ton dodge van rear leafs and homemade boomerang shackles. Check out my posts on it if your curious. I did it for half the price of new springs and it rides nice. A good shackle angle is everything.
