Can you please let me know the what the diameter of the knurled part needs to be? You can do this by measuring the lug studs you current have with a digital caliper to the nearest hundredth of an inch.

The Kodiak Wheel Bolt part # K12WB169 will be a bit longer at 1.7" long than the studs you have now but should still work for you. It has a 1/2"-20 thread and 0.545" diameter knurl. I have attached a review video on the above stud for you as well.

Looks like you have a spline diameter of .56 inches and and threaded portion of 1/2 inch which is very popular. For that you'd want the part #K12WB2. I attached a picture that has a dimensional diagram for you to check out as well.

I did some checking and the hub/drum we offer that will work for you is the part #8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS…
