Want to put some Eaton Elocker4's in the stock Dana 30 and Dana 44 axles. For the Dana 30 should I go with a 27 or 30 spline locker? Not completely sure what's involved.
Thanks,
George

X2, 4340 or 4310 27 spline shafts are up to 35's and being locked on trails tougher than 99% of offroaders would be interested in being on. That also saves you from having the significant expense of converting to 30 spline manual hubs which are not cheap. There are no worthwhile 30 spline unit bearing hubs for the Dana 30/44.The general consensus is 27 spline chromoly does the trick for Dana 30’s.
If you are running the 4.0 and wheel in a civilized manner you will most likely be good running up to 35” tires locked.

Thanks for the replies. 27 spline it is!
Which supplier should I be looking at for gear sets and chromoly axles? I know Revolution has been popular but everything I'm interested in is out of stock.

Revolution discovery are a solid choice.
I don't see '2001 Jeep Wrangler Sport' listed under the fitment tab, but do see '2004 - 2006 Jeep Wrangler Sport'. Is there a difference between those model years?

Went and looked up what I have which is RAK30-TJ-27. 27 spline shafts from Revolution Gear.
I'm also running Revo Discovery 27 in my HP30 with ARB and 35's , without any issues

The other thing is when going to 30 spl or rcv's the next weak link is the R&P.
Personally I'd rather break an axle than deal broken R&P...

They are until they aren't. We have broken far too many 27 spline inners in JV in the HP 30 we are so fond of out there that is makes no sense to run 27 spline inners. None whatsoever.What about those who upgraded to 4340 27 spline shafts and had no more problems doing extremely tough trails. What benefit would be to 4340 30 spline shafts then? I upgraded to 27 spline 4340 shafts up front and had no more problems or broken shafts. Even after doing the same trail again that broke the front shafts in the first place. I seriously believe front 4340 27 spline shafts are more than enough for 99.99% of those doing tough offroad trails. At least they were for me.
Ever wonder why the TJ Rubi front 44 came with the same 27 spline stubs and unit bearings that the Dana 30 did? The reason that it came that way is the engineers understand that when the stub shaft is torqued to spec and is clamping the two halves of the unit bearing together, there is also something else going on. What happens is the flat face at the base of the stub shaft that butts into the back of the unit bearing is creating a lot of friction (just like bolts do) between those two faces. That friction greatly reduces the load on the splines and prevents them from breaking or twisting off.Not to mention, as brought up above, the outer stub shafts are still 27 spline in many of the 30 spline shaft kits.
