I like how the PDFs show the top 5 and top 10 AVG laps.

From Slappy's advice on the 11th I will be giving the XRAY a try in MOD and moving the CRC to 17.5.

Very excited to for the next MOD race.

SO I have been staring at my 1/12 and decided it needs to make a return to the rug and completely crush the class again... umm not.

Anyways I just rebuilt the diff (CRC 16 ball spur, 3/32 balls and a Slap kit). For the freaking life of me the damn thing is completely locked up. It almost seems the diff balls are too small and the rings hit the spur first. It has to be completely loose to even move it... Tighten the nut down until the spur doesn't slip and it is locked (Can't hold one hub and spin the other).....I know it has been a while but come on!!!

WTF... over.

Why do you have to suck so much.. b6 wtf lol

But I do feel your pain. I had to borrow a steel axle for my f1 from another driver, when the Carbon one broke. It looked like the same axle. Had the same stamp on it. I spent 2 hours trying to figure out why it want working. Maybe the spring washers are flat etc. turns out it's the same axle shaft but where they pinned the flange on was different from the fx to the fxm😎🔫😭

One of the issues with running a CRC spur that takes 3/32" balls and my thrust kit in an Asc axle can be running the axle stub into the thrust race, which stalls it out. I hate to say this, but you're better off sticking with 1/8" ball spurs to get your tolerance back. You'll have to search 72t 1/8" ball spurs. RW closed up. I don't think Kimbrow makes any. I do not make a longer spacer for this scenario.

I'm not a fan of 3/32 balls.

If the axle wasn't originally designed with that intent, there is easily tolerance stack issues that result in the hubs clamping down on the inner bearing of the right hub, and the bearing inside the spur gear.

1/8 ball and be done. Usually results in a more durable diff, and there are much better quality spur gear options out there for 1/8" balls

Kyle,
I looked at your posted pic. Those 3 gold shims should not be between the delrin spacer and the hub bearing! Email me: [email protected] Lets get you back on track.

It's need to have something there, I believe, because with the smaller balls the actual graphite of the axle sticks out past the plastic spacer and the thrust assembly hits it when the nut is tight and doesn't allow the hub to squeeze the diff rings.

I was staring at that thing for.like an hour this morning... was fine, just gritty, took.it apart and put.new rings and balls and I failed!!!

WTH! LOL... I'm sure it's a DOH thing...

Acer makes 1/8 carbide balls. Broadway in Everett stocks them.

Kyle, you are trying to assemble something that was not meant to go together with the combination of parts you have. That is why you are having trouble. The Asc axle is not meant to have 3/32" balls which snowballs into issues at the thrust kit. By adding those 3 shims, you defeat the thrust kit. Trust me. Find an 1/8" ball spur. It will fix your issue.

I will source one and go with 1/8 balls. The crazy part of the whole story is that I did have it set up with 3/32 and have ran it that way. I have Jose's 10R5 on the wall at my desk and just checked and I have it set up that way also and the diff is butter. Going to check the 5.1 I got from Kody when I get home... Sure am glad him and Matt aren't on here or I'm guessing my text messages would be going nuts..

All good.. next topic is what is a racey low cut for the 1/12 spec tires?
