Replacement Lug Studs for Al-Ko 8500 Hub and Drum on 2012 Keystone Hideout 19FLB

Question

Question:

Any ideas on a replacement wheel stud? I have AL-KO 8500 hubs. I’m pretty sure it is a 1/2” thread by 2” long stud. Any help would be appreciated. Thanks

We don't have a database that tells us what the stud size is on that hub, but I was able to do a little bit of research and find some reports that say that your 1/2" thread by 2" long stud seems to be accurate. For that size wheel stud you can use the Redline # 7-122 lug studs you were looking at which are 2" long and have 1/2" threads.
