Harley-Davidson Heavy Synthetic Gear Oil 62600093 is a premium product tested and certified for use in Harley-Davidson transmission and primary chaincase applications. Exclusively engineered for Harley-Davidson Motorcycles, this Heavy Synthetic Gear Oil is designed for extreme temperature environments, making it ideal for desert heat or cold weather conditions. It is recommended for frequent two-up riding and heavy load applications.
This dual viscosity (SAE 80W-140) heavyweight gear and primary oil is formulated with proprietary additives and pure synthetic base stock. It offers excellent flow characteristics at cold start-ups and behaves like a 140 weight oil in high temperatures, ensuring maximum protection. The formulation maintains the proper coefficient of friction for clutch operation and provides superior lubrication for the primary chain drive.
Harley-Davidson Heavy Synthetic Gear Oil is specially formulated to provide exceptional lubricity for the anti-wear requirements of transmission gears across a wider temperature range compared to mineral-based oils. Approved by Harley-Davidson, this gear oil is suitable for all stages of transmission and primary chaincase life. Please note that this product is not intended for use in the crankcase as a motor oil.
