Differential heater

[james schaechter]

I tried some stuff that looked like atf. The guy I got it from said comp and prostock guys used it. It wore out the ring gear in about 6 runs. It didn't break, it just wore down the teeth. I love superlight gear lube, but this stuff did not work for me. The redline superlight weight is great and I never had an issue with parts wear. I would think the gibbs stuff would be similar, but I have not tried that. Our car was a 2900lb stick stocker Nova.
