Is it splined in the middle hole? I can't really tell from teh pictures. I assume it clamps on the outer axle shaft and then u slip the wheel on it?

Would my 12mm hexes from the clod buster fit on the wk?

I'm asking for a friend with a WK. He's buying 2.2 beadlocks and needs hexes.

use the stock hexes. i dont like those ones because they have the lip on the edge. some wheels wont work with the lip on them. i had to sand down the stock ones to use 1.9 stock car wheels.

what 2.2 is he using because the 2.2 axial rockstars fit fine
