Schumacher diff lube (period)

They invented the ball diff, no?

IMO

1. Schumacher
2. X Gear (repacked as kyosho in most places)
3. ASSOCIATED stealth lube
4. Everything else

I buy plain chromium steel balls. If I can't seem to get the diff right, I chuck all of the balls in it and start with brand new ones. I've tried the ceramic balls, and had success, but have had diffs that worked/felt just as good with the cheap balls so I have a hard time justifying the cost. $30 for a lifetime supply of Cr steel in 3/32" and 1/8" vs. $12 for 12-16 1/8" ceramic. I know lots of fast guys that swear by both.

Agree on that I recently spoke with the top driver of alien racing and he also uses steel because he can't justify the cost of ceramic. To each his own.

For the grease I used to have corally grease and moved for schumacher diff grease I use in my offroad cars

Asc 6636, end of story

Inexpensive chrome balls. Slip a ceramic, it will be junk and a waste of $.

I disagree with just using cheap chrome diff balls, from personal experience. You can buy 1/8" silicon nitride diff balls for a dollar each from a few different sources. For me this was money well spent, I have ran the exact same set of 12 for two years, and hundreds of races. Because the diff balls are so hard, the ring is sacrificial when the diff slips, instead of the ball.

Recently I compared my 'used' set of SiN diff balls to new ones and my micrometer and found they had lost about 0.0003" (not a typo, three ten-thousandths of an inch). This combo with a thrust bearing and AE diff grease (I will admit to having run Losi at one point and felt no difference) runs pretty well. It builds very smooth diffs, consistent run-to-run.

Basically, 12 bucks bought me lifetime diff balls.

-Edit: This didn't work in offroad, my B4 diff chewed itself to bits with silicon diff balls. After which I threw the ball diff in the trash and ran gear diffs in offroad, because diff maintence is for the dedicated.
