I'm going to install either a 4 or 6 inch lift on my 89 blazer. While I'm doing that I think it would be wise to switch out the axle as well. I drive my blazer to work about 2-3 days a week and I don't do any rock wheeling, but thought if I go with a lift and at least 35" tires I want something stronger. I do go off road but nothing major. Would a 12 or 14 bolt be best considering strength and price? Where is the best place to get a 12 or 14 bolt axle with the gears already installed? At least 4:10 gears I guess. Thanks, guys.
