Built my diffs today. Light sanding (600 grit) on the rings, and ceramic diff balls = the smoothest TC diff I've ever felt...period. Looking forward to get them out on the track.

I used one of the new diffs all day Saturday on asphalt and all day Sunday on carpet. Excellent! Don't think that I will be rebuilding diffs too often in the future.

If you got the wrong non-flanged bearing with your new diff you can just use one of the two from the old diff. But, not so if it was the flanged bearing.

You won't be disappointed at all.

And once again, I'd like to send out a "Rock Chalk Jayhawk" to those unbelievable new diffs!!! Once again, Corally is setting the standard for ball diffs.

What diff lube are people running in the new diffs. In the old ones I found if I used Losi brown in the thrust bearing it would hold up allot longer than the black grease. Then I would use associated stealth on the diff balls. But since there is no thrust any more I was currious to what people like to use on the diff balls.

I built my two new diffs with ceramic balls and the regular Corally diff grease. Didn't need much grease either.

No black grease anymore.

Yeah Boy...... got the diff's in all our cars this week, and even with the stock steel balls, smooth as butter. Just waiting for the next order to come in with the ceramics.

What are the advantages/disadvantages to running the 36T diff pullies vs. the 42T ones, given the same final drive ratio?

James,

The 36 tooth pulleys, in my humble opion, give the car more snap out of the corners.
The other benifet is that you can run the CEFX ackerman extension to change the bump steer. On high traction surfaces, it takes away some of the "edginess" of the car.

On a side note, I ran the new Corally 13.5 motor last night, it was definitly impressive. Had more rip than the Novak by comparrision.

Would be nice if we could get the CEFX steering extension...

An alternative to the CEFX extension is to change the ackerman by using extensions from the steering knuckles. If you have an old shock tower laying around, just use the camber link holes for the extensions, and walla, you have the same effect.

Any pics of this mod, please.

I have now modified a Xray bellcrank to replace the stock piece, this allows for the fine increment adjustments, retains the servo saver option, and all fits with a 42 pulley. It looks like I can get to within 1/2 degree of what a 008 does now. Now to test it.
