I have a 74 K5 blazer with stock 31X10.5 inch tires. I'm planning on installing a 6" suspension lift and some bigger tires. I was hoping somone could run me through what lift I should get? What I need to buy? What are the biggest tires I can put on? etc. Also, if I put on a 6" do i need to lower the transfer case, need shims under the axles, need a new driveshaft, is the driveshaft going to catch on anything? Advice is welcome!
