Red Line V-Twin Primary Case Oil (Set of 12 x 1 Qt. Bottle) 42904

Red Line V-Twin Primary Case Oil is specifically formulated for American V-Twin motorcycle engines from 1984 to present, including aftermarket engines with similar designs. It functions similarly to Red Line MTL and is intended for use in primary chain cases with wet-diaphragm spring clutches. This synthetic oil is designed to operate effectively across a wide range of temperatures while enhancing clutch performance and reducing wear and tear. Unlike some synthetic lubricants that can cause clutch slippage, Red Line V-Twin Primary Case Oil's friction-balanced formula minimizes slippage, promoting smoother operation and enabling better power transfer in modified engines.
