Red Line 75W90 Gear Oil

• Most popular Red Line gear oil, with thousands of applications for passenger cars, light trucks, and racing vehicles
• Contains additional friction modifiers for suitablity with clutch-type limited slip differentials - for most LSDs, no additional friction modifiers are required
• This product is not designed for use in most manual transmissions or tranaxles, since the extreme slipperiness may cause synchronizer mesh issues that lead to shifting problems
• Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360

fits: Sporster Primary and gear combination
