Gearheads and serious racers, this Red Line Shockproof gear oil is some next-level stuff for high-performance applications. We're talking about a unique lubricant that contains microscopic solid particles suspended in the oil - these act as extreme pressure agents that provide incredible protection under shock-loading conditions. The 'Lightweight' version gives you the film thickness of a heavier SAE 250 grade oil but with the low fluid friction of an 80W140, which is pretty amazing when you think about it. It's specifically designed for heavily-loaded racing differentials and transmissions that see serious shock loads - think offroad racing, drag racing, or any application where your gears are taking a beating. The viscosity characteristics resist throw-off while providing superior film strength, and it actually has better cold-flow properties than you'd expect, making shifting easier when things are still cold. One important note: it's generally not recommended for most synchro-type transmissions, so check your application carefully. Whether you're dealing with problem gearboxes, maximizing power transfer in racing differentials, or just want the ultimate in gear protection for severe service, this Shockproof gear oil delivers performance that conventional oils can't match. The 1-quart bottle is perfect for most differential applications or for mixing with other fluids for specific needs. If you're pushing your equipment to the limits, this is the gear oil that can handle the punishment.
