3 Spectro Heavy Duty Synthetics
This unique lubricant was developed for Harley-Davidson owners who were unhappy about their noisy 6-speed transmission. It provides smoother shifting, reduces fifth gear whine and eliminates clunks.

High loads and extreme heat do not affect the oil, so it performs excellently when pushed hard and long. A.P.I. GL-5 rated. Dyed red. Exceeds all known OEM and Harley-Davidson warranty requirements.
Engineered specifically for Harley-Davidson high-performance engines and other high-output V-Twin motors. Spectro Heavy Duty Platinum Full Synthetic uses our G4 Technology to dramatically increase throttle response and horsepower.
