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.
This product is a heat transfer fluid for the clutch as well as a lubricant for the chain and sprockets.
