Wheel Stud Length when adding 19..5

[LMarler]

I just installed a set of Rickson's 19. 5 on my 06 DRW truck. I bought these from a fellow TDR menber. When mounting I noticed that wheel stud is shorter, the nut is about flush with the stud may one thread out. I am sure other have been down the same road, do you think it will be OK or should studs be changed out to longer one's? I went on and installed them, torqued to 140 lbs. drove 2-3 day 300 miles rechecked all good. Still would like some feedback!

Thanks,

Lynn

This is fine... as long as you have 1/2 a thread showing you have full contact of the nut to the stud. .

After reading Jim's reply, I got to thinking I my not have been clear about the stud length. The studs on my truck are not threaded all the way to the end, maybe 1/4" back threads stop. I should have said stud sticks out maybe 1 thread. So about 3/16" of the nut isn't making contact with the stud!

Thanks,

Lynn...

Nope, your in trouble... you need 100% thread contact for the full length of the nut to secure the wheels correctly... I'm guessing if you drove it like a car you'd have no problems because of the safety factor... but using it as a truck its not good...

Before I thought about changing the studs... I'd contact Rickson via email and see if the structure of the wheel would still be sound if you had a local machine shop use a cutter to cut a recess in the allow wheel to allow the nut to sit deeper into the wheel or if Rickson has a nut they suggest that will do the job...

If you were using this commercially you'd be red tagged and put out of service...

I've not paid much attention to these wheels... all my trucks have steel wheels we had made... . I can only assume you don't have a spacer or anything you can remove and still have proper tire spacing...

I have decided I need to change out OEM studs. I just don't fill good knowing they are short. I would like to find longer studs, but I'm not able to find one that is just longer. I have done internet searches, TDR treads and local auto parts " napa & carquest" without any luck finding one that is just longer. I know I can't be the only one that has run into this problem. Someone will have the answer I am looking for!

Thanks,

Lynn

You don't say where you are... . you need to find a Euclid, Dayton, Sirco, BWP distributor in your area... they will have a catalog based on diameter and length... what you'll have to find is another stud, designed for a different vehicle that uses the same size hole and press fit. . but one that is longer... Call one of your truck distributors (MacK, Kenworth) in your area and find one that has a catalog... if you have a NAPA store with a HD specialist, not just a counter sales guy, he should be able to help...

You actually need one stud diameter of thread engagement. The Dodge lug nut has . 875" of thread, but the stud is 9/16" (. 5625") diameter, so there is sufficient engagement. The lugnut is longer than it needs to be to allow for the ridge that the center cap snaps over and still have a long enough hex for the lug wrench to engage. Sterling offered aluminum wheels as a dealer installed option on the 4500/5500 and simply went to a shorter lugnut where there were a couple threads sticking out past the nut to get around the problem. Jim is correct in that DOT wouldn't like it, but if there were a shorter lugnut, they wouldn't give it a second look. If this were a problem, it would have had to have been addressed years ago.

Heather... .

You might consider asking an engineer for his comments... My boy is a mechanical engineer with his PE... and he disagrees with your comment... I suggest that your suggestion might compromise the safety margin built into the design!!

Jim --just so happens this is information is in fact directly from a very experienced mechanical engineer. Directly from my boss, the president of Rickson, Dan Richter.

I have done some research on this, I spoke with Bob at Rickson and he told me the same thing as Heather is saying. I also spoke with tech support at Dorman Automotive Industry about a possible different stud. They back up Heather & Bob about wheel stud length's on Dodge and some Fords. There is a stud that will work, but it would take some milling on hub to be perfect. Napa #641-2181 the Knurl and shoulder are slightly different. The front wheel spacer would not be a problem, but the rear hub might be!
