EXTREME DUTY PRIMARY OIL
S&S Cycles new Extreme Duty Primary Oil is formulated specifically
for use in primary chain cases of Harley-Davidson big twin and
Sportster models. This is a petroleum-based lubricant with high shear
stability and the ability to withstand extreme loads. Special polymer
additives allow it to remain stable at elevated temperatures and provide
exceptional clutch engagement. The SAE 85w viscosity provides low drag
and frictional losses and eliminates clutch drag and slipping.
