75w140 Pro Gear Oil 1 Quart

The 75w140 Pro Gear Oil 1 Quart from Maxima Racing Oils is a synthetic gear lubricant engineered for high-performance transmissions and differentials that demand superior film strength and thermal stability. This product is designed for drivers and technicians who rely on consistent power transfer in extreme conditions—whether in racing applications, heavy-duty off-road use, or precision automotive environments. A single quart bottle provides convenient top-up or partial-drain maintenance without committing to larger quantities.

Synthetic base stocks in this 75W140 formulation deliver robust viscosity control across temperature extremes, maintaining protective film thickness under shock loads and sustained high-speed operation. The 75W cold-flow rating ensures reliable startup performance even in cold climates, while the 140 hot rating provides maximum shear resistance during aggressive driving or sustained load conditions. This viscosity grade is particularly effective at reducing gear noise, wear, and friction while resisting oxidation and deposit formation—critical factors in transmissions and differentials exposed to sustained high pressures and thermal cycling.

This Pro Gear Oil is ideal for drivers with manual transmissions, limited-slip differentials, and gear-driven transfer cases who require a premium synthetic option beyond conventional mineral oils. The 1-quart bottle format suits maintenance routines, emergency top-ups, and test applications before committing to a full fluid change. Verify compatibility with your specific transmission or differential manufacturer's recommendations before use; most high-performance and racing platforms benefit from the enhanced thermal and shear protection this synthetic formula delivers.
