I've currently got Ford keys in the front and an add-a-leaf in the rear. I like the rear 1" higher than the front empty. I'm running Dick Cepek 33x12.50x17 tires on MotoMetal rims. I'd like a couple more inches of lift to complete the look. My truck is rarely off road. So I don't need anything stronger than stock. I don't need double shocks or anything like that. I don't want to increase the track width like some lifts do. What would you suggest, keeping budget in mind?
