De-Tuning of Gear Lube for LSD
NEO Gear lubes are designed for racing transmissions / LSD assembly's. The gear lube is designed to limit the slip of the LSD. In isolated cases were the gear lube is limiting the slip of the differentials too much, you need to contact NEO to obtain an additive to increase the slip in the LSD. This is the fine tuning or de-tuning of the gear lube.
