hey all...new to the forum. just finally got myself an 85 gmc 4x4. it already has a 4" lift on it,,but i would like a little more. would a tuff country add a leaf up front do anything? would i still get 2" of lift? i want to keep this truck as low buck as possible. it will never see the road,,and be strictly off road. i also am not overly concerned about ride.
