No. You do not need/and should not use a special oil lubricant, limited-slip additive, or friction modifier when using Traction Concepts Limited Slip Differential (LSD) Conversions. Adding friction modifiers can reduce the functionality of a disc-type limited-slip differential by making the faces too slippery. This counteracts the friction necessary for our Traction Concepts Limited Slip Conversion to work properly, leading to a loss of the primary function it was designed for. You can continue to use a high-grade synthetic oil recommended by your vehicle's manufacturer or the one you’ve been using for optimal performance.

If you're engaged in endurance racing, we suggest changing the oil after approximately 20-24 hours of hard use to ensure your LSD remains in peak condition.
