Has anyone used a Rancho kit to level the front of their Ram? I've got an 01 2500 4x4 with a front end replacement on it that's about 4 inches lower in the front than the rear. I called Rancho the other day and they have 2 kits for this truck, RS6576 which is coil spacers and lower links and RS6566 which is spacers, lower and upper links, and dual shock brackets. I'd like to lift the front 2 or 3 inches and was checking if anybody had any experience with the Rancho kits. Thanks.
