8.25 rebuild - Any tech advice?

I would definitely recommend it as the factory 27 spline axles are tapered, whereas anything you order (as well as the 29 spline Dakota axles) are straight shaft with no taper.

Talk to Doctor Diff. I will be getting my axles from him since he knows Mopars and can get axles made cheaper than Moser or Strange. Might not be "as tough" but in reality they are WAY overkill for my needs. I did the math and the cheapest Moser axles can take something like 300% more torque than my car can make....LOL.

I bought my C-body brake upgrade lines and brackets from him....helluva guy.
