quick change ???

ok I got a Frankland Quick Change rear end under my 31 sedan. The bolt pattern is 5x5. It came out of an old race car and has large wheel studs. Not sure size but big. The question here is I want to run American racing Salt flat wheels. OK here is the deal. The center of the QC has a part that holds the axle in. Well this part is 3 in. wide and cone shaped. The wheels I want have a 2 3/4 in center hole. So if I machine the center to make fit over the cone, then what do I do about the large wheel studs??
Thanks

 

Can't you just put smaller studs that have the same size mounting shank?

 

I'm a painter by trade so not to hip on changing stuff out. My guess was if I put smaller studs in it, I would have to weld around the holes?

 

Those wheel studs are probably 5/8 and have an even larger shank so you'll not likely find a regular stud to fit it.

One thing you might be able to do though is to make a sleeve to press (or preferably weld) into the hub and use a smaller drag racing style stud that has a nut on the back of it for retention.

The hubs should be beefy enough to drill and install a sleeve large enough to be able to tap for the drag style studs.

Can the studs be machined down and then re-threaded?

 

That hub is a standard ( as much as anything is standard LOL !) race car part.
If you order your wheels from American racing they will drill the stud holes to the proper size for you. Just spec the center hole and stud size when you place your order.
good luck

on the studs what we do i take them out and drill out the holes and put heli coils in that are 1/2 " and use studs that are threaded on both ends out by the drive plate the cap you are talking about it has 3 screw in it that thing is so you can get the wheel on fast and to alin the studs on the wheel easy just machine it down to a 1/4 " or make a new cap it is gust holding the axel from coming out and loading the end play.

i hope this helps >> Clay

 

Thanks for all of yall for your suggestions. A friend that races told me today to maybe turn down the studs and retread them. Heck I guess I'll see how it goes.

The studs are 5/8 probably co**** thread. The wheels I run don't come drilled for the 5/8ths studs so I just drill them out, then touch up the bevel with a counter sink so the nut surface mates up properly. I've been running them like this for 10 years. I've only tore one wheel up that hadn't made contact with a large hard object, wall, compe***or, etc.... That night I broke a brake caliper and took the rotor hat off along with the caliper. The wheel didn't seat properly and wallowed the holes out. I think it would look cool with large studs and double sided nuts, maybe aluminum.

 

Can't you drill new smaller holes in the hub, in between the original stud holes?

3" sounds big for the drive flange on a 5x5 hub. Could it be turned down and reduced in size on a lathe?
