Hi guys, I have a mud bog\race coming up in a month and going to need a super strong rear drive shaft. I pulled the rear u-joint threw the end of the drive shaft at the spring race. I have aprox 600hp 406 with nos in my YJ. I had a home town shaft/machine shop make the first one. Obviosly not strong enough. Any help would be appreciated.

no matter what shaft you get you will still be stuck with the weak stock u joints.... look into upgrading the yoke(s) to handle a bigger 1350, 1410, etc u joint....

Tom Woods. Get a bigger U-joint too or you will be blowing it up too.

as previously stated the shaft isn't the weak link... it's the u joints....

you could make your own with ease, just use larher joints/yokes. note: you will have to match them at your tcase also....
