LSJ vs LNF axles
I see threads on occasion asking if they can run LNF axles on LSJ or the other way around. i'm actually swapping to LNF axles on my car but it is not a direct swap, there's more to it than just changing axles.
But i figured while i'm at it i'll take measurements and show you guys how they're different.
As we all know, both cars use the F35 transmission or MU3 code. so both transmission shafts are the same spline count and diameter, the difference comes in the main shaft and hub shaft.
Now the axles with the blue boots are actually DriveShaftShop level 2 axles for the lsj, but because they are direct replacement the only difference will be in the material used. And possibly the main shaft diameter, not 100% sure i'll find out when i measure my stock ones. But even still, the LNFs are still larger
LSJ in the middle. LNFs on either side.
Just by looking at them you can tell how much larger the LNF axles are. and these are just my measurements. but i'd still say its +/- 0.5mm
being the same on the transmission side, both axles are:
27 spline count
30mm diameter at the splines
35mm diameter at the lip before the case (shown in picture 3)
Now the differences.
The LSJ axle has a main shaft diameter of just 25mm. (measuring a DSS axle, oem is still the same i believe)
The LNF axle has a main shaft diameter of 34mm.
The LSJ hub spline count is 33, with a shaft diameter of 26.5mm
The LNF hub spline count is 30, with a shaft diameter of 32mm
One last comparison. LNF axles in LNF hubs. Top looks like it doesn't fit just because it's dark, it fits lol.
This however does not fit. LSJ axle in an LNF hub.
Can you run LNF axles in an LSJ though? Yes you can. You can do it with or without ABS as well. For me i didn't care about abs and just did a straight swap of LNF control arms, hubs, knuckles, and axles. In order to maintain ABS you will need to run either the GMPP wheel hop kit, which utilizes a combination of both cars i believe. Or run the Powell Race Parts swap and have everything custom machined. But as far as a direct swap goes, no it's not going to happen.

Would you happen to know the part # on the bigger beefier axles? Or where you purchased them.
I've been trying to get some and cant find them anywhere...I dont need the kit, just the axles. I already have the hub an such...

Yeah they've been selling them for a while now, I just like having the larger outer spline. And ABS wasn't really an issue for me. This was really more meant for the people asking "Does anyone really know the differences between our axles?".

sorry if this was said before and I missed it but am I correct in saying the following:
the gmpp lsj upgraded axles are lnf axles modified to fit the lsj hubs?
or are they just beefed up lsj axles?

bump for this question! ZZPerformance - GM LSJ Upgraded Axles #GM-10222413 x2

Or when you have opposing angles like say a 90* inside a differential or rear end. I use that example loosely though because those threads are normally deeper, just depends on material and cut.
But as you can see the LNF axles are almost a full 6mm larger in diameter on the hub splines than the LSJ axles. And they aren't transferring power in the sense of the word that you most find when normally talking about gears and splines, like above. It's just simply resting inside the hub helping the hub turn, at the same time, at the same speed, in the same direction.
