A straight axle is one option.

I may be hard to believe, but the Ford 9" is the diff. of choice. Of course you loose the IRS, but that's all part of making the rear end so much stronger!

..... I've been pounding the D44/IRS with approx. 600hp for a while … the worst I've done is break a few U-joint caps … presently running a custom spool …..
