School me on 35 spline

[pkrfctr]

Front axle is a Frankenstein- Front axle – ’03 ford f-350 superduty srw, long side shortened 1”, short side lengthened 3.125”, diff moved center 2.125”, axle wider 2.125”, inners 35 spline, 30 spline outer, short side 78-79 ford f-350, long side 88-98 ford f-350.
I have broken 2 stock stub shafts on the long side (stock hubs) and 1 chromo stub (warn premium hub). Thinking its time to go to 35 spline. So looking for input on what parts to use and any surprises. I do run 60 tooth tone rings so the computer is happy. Its a must to keep those, I cant stand dash CEL lights on.
What breaks next once I switch to 35 spline????

You'll need 35 spline outers and either hubs or flanges. Upgrade the u joints and go flanges if your worried about breakage. Then you'll start breaking inners, but unlikely

I'm fine breaking hubs and would prefer that but I've yet to lose a hub without losing a stub. Ujoint is a Spicer spl55

I'm 95% sure the '99-'04 unit bearings need to be bored out to fit 35 spline stubs, and then the stubs themselves and hubs/flanges like @Kiel mentioned. @skippy or @Agility Customs could confirm that...

That is correct bore the unit bearing out to fit the 35 spline shaft or buy them already done from Branik, or spidertrax or trail gear.

I ran 35 spline outers, Warn hubs, 4130 shafts and Spicer 1350 joints with HEAVY 40's, a V8, Atlas in my old TJ and didn't have any issues with breakage... and did plenty of front digs and stupid on-the-throttle driving. 😁

I think once you upgrade to 4130 35 spline shafts and a decent u-joint, it will take some real trying to find the next weak link.

Anyone have experience installing tone rings into the branik unit bearings?

I run 35 spline 4130 Yukon inners and outers and broke a 35 spline warm premium hub before breaking a spicer u-joint... Swapped to Teraflex flanges and haven't had issue since. Thinking of having branik machine my axle shafts to turn tighter and then I'd definitely swap to a higher strength u-joint.

Branik just machines an OEM unit bearing so pressing on the tone ring should be GTG
