Extreme Performance V-Twin Primary Lube is designed for use in the primary chain case of all Harley-Davidson Big Twin Models and in the wet and primary/transmission common sumps found in Harley Davidson Sportster models with wet clutches sharing the same sump as the transmission gears.
Extreme Performance V-Twin Primary Lube is made with the finest severely hydrofinished polyalphaolefin (PAO) synthetic base fluids and severely solvent refined, severely hydrofinished 100% pure paraffin base oils. Further blended into Extreme Performance V-Twin Primary Lube is an advanced additive package and Micron Moly® to create a powerful defense against wear and premature component failure.
Extreme Performance V-Twin Primary Lube can be used in chain chases equipped with original, modified or aftermarket high performance clutch assemblies. (Not recommended for combined engine/transmission sumps.)
