Hey Ron,

To the best of my knowledge there are three C5/C6 hubs: the standard C6, the Z06 which LG Motorsports sells with the larger rear bearing and the ZR1 which I believe is still only available at the dealer. I could be wrong, but as far as I can tell the ZR1 is the same as the Z06 with the exception of the ABS sensor and inner spline count. Do you know if the load rating is any different for these hubs?

Hey Ron,

Yes, in that bearing you're referring to, the outer bearing is larger than the inner bearing & it is stronger. This makes the hub rated higher overall. But the weakest bearing is always the bearing that fails, regardless if it's on the inside or outside. The small one in the Z51 bearing is the same size as before, rated at 1060#.

As I mentioned in a previous thread, the bearing engineer I work with said this bearing will wear quicker than the big bearing stuff we're used to racing. So if you check the wheel/hub play & it starts to show excessive, simply replace it. If that happens often, then maybe you need a stronger spindle/bearing/hub assembly. If not, you're probably fine.

Ron, can you find out if you can get me a good set of bearings for a C4 hub?

You have a Baer hub which is basically a factory GM drum hub.

I remember a few years back...90's someone had a first gen hub that ran a larger outer bearing. I tried searching around but can't seem to find it here. I believe it was Herb Adams could be wrong.

Tobin makes a billet hub but I am unsure what bearings are used.

Tobin uses stock replacement Timken bearings for his hubs.

Thanks Tu, I wasn't sure.

On my '67, Maeco used either second gen hubs or SCP hubs on a custom spindle that had the big outer bearing. At the time, Mike really felt that was critical on the race applications. I don't think I've ever seen a first gen throw a shoe though, but I'm sure it's been an issue here and there.

Personally I haven't witnessed any failures on properly maintained cars. Most where due to neglect, lack of grease and improper free play.
Im not sure how long Gaetano went on his very first set before coming to me but there was a layer of dark grease at the outer bearing. I believe it was right after the 341. If he had a season on them its doing good. So far his bearings look fine but they normally get serviced 3 times a year.

I was actually going to come back and mention that... I've seen a fair number of crazy failures of all types at HPDE events, but not on the vintage race cars.

We had to change the seals on the caliper pistons every session when I ran the J56 4 piston brakes on the front because I didn't have a set of the sexy insulated pistons (which is why we went to the CNC brakes fairly quickly!)...

I didn't mean to say that I hadn't seen it, to dismiss it. Just an off the top of the head comment and absolutely related to the level of maintenance that goes into running a heavy, high power race car.

Makes perfect sense Ron. Thank you Sir
