How good is a 12 bolt rear? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 1978 12 bolt rear with 4.56s and a spool. The front is a 10 bolt 4.56s and a lockright locker. How strong are these things? I know I would be better off with a 14 bolt and a d60 but this is what I have. So what are your thoughts on this being used hard off road. What can I do to make it stronger. I think the rear is a 30 spline and the front is a 28 spline, is that right?

I am new here. I come from a Jeep forum. I have all Chevy running gear in my Jeep, from motor to rearends. I get good Jeep stuff info from those guys but I'm hoping you guys will be able to help me out with all my Chevy questions.
