▸ Primary Chaincase Oil

Lucas HD Primary Chaincase Oil is a blend of easy flowing base oils and a Lucas additive package designed to carry away more heat from the clutch plates and friction plates. This assures a longer more trouble-free clutch life.

Expect a smooth clutch action, less slippage, longer chain and sprocket life and a much longer oil life.

Remember

Primary Chaincase Oil is a coolant for the clutch, not a lubricant.
