2006-2010 Commander wheel studs are .667 knurl diameter, .781 knurl length, 1.906 under-head length, 1/2 x 20 thread. And to the OP of the thread, good luck finding anything. You wont. I've been dealing with this for the last week and a half. I've spoken to ARP, various 4wd shops, Moser Engineering, Moroso, and have emails to a few other sites. You can call ARP manufacturing at 805-525-1497, and ask for special orders and give that a try, but i doubt they will make just 20, and if they do, it prob be pricey. Im trying to clear calipers for JK Moab wheels, and i wanted a wheel centric/hub centric spacer (with its own hub lip to fit in the wheel) just to clear the brakes. The factory hub sticks out 5/16", so the thinnest anyone would make wheel centric/hub centric spacer is 7/16". So i was looking for a oe size stud, just 1/2" longer. No dice. Spoke to Jason at Moser Engineering, and his idea wasnt bad either. You could go with their 8620 wheel stud, but the knurl diameter is .685, and thats gonna be tough to press into the hub unless you use a 43/64" drill bit to chase the holes in the hub. They're also a 3" length. I asked about cutting them down to 2.4", and my concern with heat on them from a cutoff wheel, and he said you aint gonna hurt them. I've decided to grind the calipers, and go from there. Hope this helps. JB
