i have two questions actualy the first is i have a 1/2 ton 05 silverado i was wondering if there was a way i could change out the rear leaf springs with a 3/4 ton eg. what year will fit if at all, to make my truck into a heavy half. the second question i have is if there was a way i could change out my front calipers and rotor for an 04 silverado so that way i could fit 16'' tires on it . if anyone has done this or has any insight on it i would appreciate it.
