Red Line V-Twin Primary Oil Quart

Ensure maximum power transfer and extend the life of your clutch and primary chain with Red Line V-Twin Primary Case Oil (Part #42904), available now at RB MX Parts. This full-synthetic, friction-balanced GL-4 fluid is engineered to withstand the intense loads and heat generated in high-performance motorcycle and Powersports primary chaincases.

While designed for American V-Twins, this formula's exceptional film strength and balanced friction make it a superior choice for any wet-diaphragm spring clutch system requiring specific, non-engine oil lubrication, preventing the dreaded clutch slip.

Key Performance Benefits for Powersports Drivetrains:

• Friction-Balanced Clutch Performance: Formulated to optimize friction, ensuring positive, predictable clutch engagement and maximum power delivery without slippage.

• GL-4 Gear Protection: Provides superior anti-wear and Extreme Pressure (EP) protection for the primary chain, sprockets, and gears, unlike standard engine oils.

• Reduces Operating Temperatures: The stable ester base stocks effectively reduce friction and heat, promoting cooler running temperatures in the primary case.

• Shear Stable Synthetic: Resists viscosity breakdown under heavy use and mechanical shear, maintaining consistent performance through long rides and hard racing.

• Extended Component Life: Protects seals and primary components, reducing wear and maintenance frequency.
