The gray one's hands down.
They won't loosen and they hold better.

First measure your old hub, I think you will find the orange one will be
too small. Also the orange one is a real pita because of the bolt setup.
Gray one is really good, has studs measures 7 1/4" across. bolt center across the hub will be 6", stud center to to next stud will be 3" also as
Wolfman mentioned, easy to adjust and, holds tight. On my old hub I tack welded the bolts in reverse of the original setup so it out the front like studs....sure makes it easy to remove and, install the wheels.

I swapped my stock one for the grey version several years ago and they work great.

I must be losing gray cells faster than I feared and I stand corrected. I just went and looked and I actually used the gray not orange type when I replaced the worn out OEM hubs on my tractor. That was many years ago and unlike the OEM (orange) style they have been totally trouble free..

Another vote for the gray ones. My original hubs are like the orange ones and no matter how tight you get them, they will loosen back up at some point and wobble.

I picked up some gray ones from the Bay of E and have had no issues with them.

Grey ones on my tractor as well. Heck of a lot tighter then the bolt style. Easier to remove imo as well

If you are a cheap dutchman like me, you can take a grinder to the originals, open up the slit a bit and then they'll clamp down again nicely.
