Local Racers are thinking it is GPM Ball diff, and wondering if I could get confirmation. I would like to switch to 64 pitch spur and wondering if any one could recommend a spur that would fit using the existing balls, looks like the measure .124-.125 inches.

Not to many people using red anodizing. GPM, x-power are two

Thanks for giving me another possibility. After looking into both of those I think the GPM looks to be the one. However I do not see any 64 pitch spur gears on there site.

So based on the diff balls being .125" would any other spur gears out there work with these, or would any other spurs with that use a different size diff balls work?

Thanks,
Rob

those diff balls don't fit any other spur gear (and Ive pretty much used them all.) Kenon offers diff balls for sale to fit their 64 and 128 pitch spurs but if it were me I'd choose a whole new diff...you'd get better adjustability and smooth action out of almost any other choice. ;)
