Red Line Synthetic Heavy ShockProof Gear Oil 1 Quart
If you’re pushing your Corvette harder than the engineers ever imagined, you already know your diff and gearbox take a beating. That’s where this heavy-hitting, low-drag gear oil steps in. It’s thicker than a 75W250 when it comes to protection, but it behaves as smooth as a 75W90 so you don’t lose power to fluid drag. It’s built for the ugly stuff: high-heat, high-load, high-abuse racing diffs, spools, Detroit Lockers, and all those gear setups that love to complain when you hammer them. This formula uses microscopic shock-absorbing particles that literally cushion your gear teeth, helping prevent the kind of tooth breakage that ruins weekends. Just don’t throw it in a synchro box, because it’s so slippery your synchros won’t stand a chance. If your Corvette sees serious track time, big power, or you’ve just got a habit of driving it like you stole it, this fluid keeps your gears alive when everything else wants to tap out.
