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.

Can be used in sportster trans/primary oil.
