Yota Tony 07-28-2006, 08:03 PM I know that the Ford 9" is a plenty strong axle. I'm just wondering if it can hold up to some large tires (42s). I'm not running that size of tire next but one day I hope. It be nice not to swap both axles again. duffxj 07-28-2006, 08:52 PM a 9 can be built to handle 42 but it will cost some money to do it. best bet would be 60 or 14 bolt. 14 bolt is plenty strong and cheap. if you eventually want to run 42's just swap in the stronger axle now and be done. kris1351 07-29-2006, 05:21 AM A 9" with 35 splined shafts will hold 42s with no issue at all. The 9" will actually handle quite a bit bigger, the pinion is larger than a 60. You can't go wrong with one IMO. Plato2k5 07-29-2006, 07:07 AM one reason 9" are so strong is because of the pinion support they have. Just get the daytona pinion support as it uses a bigger bearing. Than do 35spline currier, or mosser shafts and you should be alrite. Than i'd truss it to JEEPRZ 07-29-2006, 09:09 AM I wouldnt run a 9" with tires that big, at least not a SF with stock tubes. Yota Tony 07-29-2006, 01:27 PM I would fully build it before going to that large a tire. I only plan on 38s to start with. 4x4 Pete 08-04-2006, 06:08 PM Why bother? D60's are cheap. duffxj 08-04-2006, 07:46 PM Why bother? D60's are cheap. i agree if your already planning on 42's you might as well put it a 60 or 14 bolt. 60 rears are cheap its the front that will cost you some coin, especially the HP fords nissancrawler 08-04-2006, 08:14 PM A 9" with 35 splined shafts will hold 42s with no issue at all.

You have to get a new aftermarket carrier with oversized bearings when you go to 35 spline. currie has them. Yota Tony 08-06-2006, 04:36 PM Why bother? D60's are cheap. Maybe in CA but they are pricey here in the frozen north. 4x4 Pete 08-06-2006, 06:52 PM Maybe in CA but they are pricey here in the frozen north. Plenty for sale on this forum at a good price. Building a 9" to be as strong as a stock D60 isn't the cheap way either. Some guys don't like the D60 because of ground clearancs, but with 42's, that's not a big problem. Anyway, i'm just throwing the option out there. You're free do do as you please. Yota Tony 08-06-2006, 08:31 PM Shipping an axle from somewhere in the US to here would be pricey. I'm not running 42s till later. KiGrind 08-06-2006, 09:29 PM Why bother? D60's are cheap. For some people, yes. Consider that. jeeperak 08-06-2006, 11:14 PM as long as your not running crazy horse power to it it will be fine | |
