Harley-Davidson Heavy Gear Oil

TESTED-CERTIFIED for use in Harley-Davidson transmission and primary chaincase applications. Exclusively engineered for Harley-Davidson motorcycles, this Heavy Gear Oil is intended for use in extreme temperature environments (desert heat or cold weather), frequent two-up riding and heavy load riding applications.

• Dual viscosity (SAE 80W-140) heavy weight gear and primary oil

• Developed with synthetic base stock and a small amount of mineral oil to aide in solubility of the proprietary additives

• Flows better at cold start-up like an 80 weight oil and behaves like a 140 weight oil at high temperatures to provide maximum protection

• Formulated to maintain the proper coefficient of friction for clutch operation and to provide superior lubrication for the primary chain drive

• Formulated to provide specialized lubricity for the anti-wear requirements of transmission gears across a wider temperature range than mineral based oil

• Approved by Harley-Davidson for use in all stages of transmission and primary chaincase life

• Not for use in the crankcase as a motor oil

• All H-D Transmissions and the following primary chaincase applications: ‘71-'22 XL, ’83-'84 XR1000, '08-'13 XR, and '84-later Big Twin models. Not for use in '21-later Revolution Max, '02-'17 VRSC or '15-'21 XG models.
