• Same fluid as our famous MTL gear oil
• This product is for use in the primary chaincase with wet-diaphragm spring clutches.
• Improves clutch operation while reducing wear and temperature
• For 1984-to-present V-Twin American motorcycle engines, including Evolution, Twin Cam, and aftermarket engines of similar design
