I'm not having much luck searching the message boards or internet for information on longer wheel studs for my '91 YJ with the Dana 35C rear end. I'm running Weld Super Single 15x8 wheels and the stock rear studs only provide a few turns of thread exposure. I haven't had any issues as-is, however, its a problem that I want to solve. I see many others with the same issue so I'd like to start this thread to be the definitive source for options and solutions since it doesn't exist elsewhere.
The stock wheel stud specs are:
Mopar part number: 83503053
Overall length: 1-15/32" or 1.46875"
Knurl diameter: .618"
Shoulder or Knurl length: 31/64" or .484375"
Stud type: Serrated press-in stud
Alt OE part numbers: Dorman 97000 or 610-364; Omix-Ada 16714.08 or 83503053
I've got the stock axle and brake setup and I'm not looking to change that. What I'm looking for is longer wheel studs with the same stock spec except for longer overall length, say 2" to 2-1/2" or so.
I've seen one suggestion that recommends Dorman 610-449 but those are .627" knurl diameter and admittedly
tough to get on and the shoulder/knurl length is longer @ 11/16" or .6875" so I'm wondering if that causes a problem with the drums or seating of the wheel since the shoulder/knurl diameter is larger (.627") than the stud and would stick out of the drum more being longer. I'm sure some compromise to the stock specs would be ok, like .620" knurl diameter or 1/2" shoulder/knurl length, so let us know your thoughts, suggestions, or experience.
I've also emailed Dorman directly asking them to cross-reference the stock stud specs and provide a suitable longer alternative, but nothing back from them yet.
Please refrain from providing useless respones like: "Get a new axle - The Dana 35C is a piece of junk" or "Get wheels that fit the stock studs" since I'm happy with my setup as-is. I'm just looking for a solution for longer wheel studs. Wheel spacers won't work either since the wheel offset is correct with these Weld wheels and spacers would compromise that.
