Red Line Motorcycle V-Twin Primary Case Oil
Product images may differ from actual product appearance.
Red Line's new V-twin Primary Case Oil is designed specifically for '84-to-present V-Twin American motorcycle engines, including aftermarket engines of similar designs. Similar to our MTL, this product is for use in the primary chain case with wet-diaphragm spring clutches.
Designed to operate over a wide temperature range, this Primary Case Oil improves clutch operation while reducing wear and temperature. Where most synthetics are too slippery for clutch operation, this friction-balanced product is balanced to provide less slip, smoother operation, and helps to apply more power in modified engines.
