58304 : 75W90NS SYNCHROMESH OIL US QUART

• Designed for transmissions and transaxles - helps to slow synchros for easier shifting across a broad temperature range
• Popular in Ferrari, Porsche and Subaru transaxles
• Musclecar applications like Ford Top Loader, Borg-Warner T-10 and Super T-10, and Muncie transmissions
• Contains extreme pressure additives like our 75W90 GL-5 oil, but lacks friction modifiers to balance slipperiness
• Improved copper corrosion protection to prolong synchro life
• Helps with lock-up on weak limited-slip differentials-compatible with Red Line Limited Slip Friction Modifier for tuning slippage
• Also used with clutch-type LSDs in racing for maximum lock up
• Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E and SAE J2360
