Red Line Synthetic 75W90 High Performance Gear Oil 1 Quart
Your Corvette's rear differential takes a beating every time you stomp the loud pedal, and that means it deserves something better than bargain-bin gear lube. That’s where this Red Line differential oil comes in. It’s fully synthetic, built from high-end ester base stocks, and slick enough to keep your Corvette’s gears cooler, quieter, and happier even when you’re driving it like GM intended. Just don’t dump it in a manual transmission unless you enjoy crunchy shifts, because this stuff is so slippery it’ll make your synchros abandon ship. But for automatic Corvette differentials, it’s the good stuff your rear end has been begging for. Check your service manual for the right capacity, pour it in, and enjoy the smoothness.
