High-Performance Racing Gear Oil 3.78L: Ultimate Protection & Efficiency

Upgrade your racing differential and transmission protection with our high-performance gear oil, boasting a film thickness greater than SAE 75W250 while maintaining low fluid friction similar to 75W90. Perfect for heavily-loaded racing differentials and problem gearboxes, this product is a favorite in various performance racing applications, including Sprint, Midget, Dirt Late Model, Quick Change Differentials, Detroit Lockers, spools, and NHRA Top Fuel and Funny Car rear ends. Note that it is not recommended for most synchro applications due to its extreme slipperiness.

Our fully-synthetic formulas, created from polyol ester base stocks, deliver excellent lubrication under extreme conditions. These products contain essential extreme pressure additives for ultimate protection in road cars and racing vehicles, as well as friction modifiers (except NS) for proper limited-slip operation. The ester base stocks and friction modifiers further reduce operating temperatures by lowering sliding friction in hypoid gears. With a high viscosity-index (VI), this gear oil provides relatively constant viscosity and film thickness despite temperature changes, ensuring superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils. It exceeds API GL-5 specifications and is engineered to offer the highest degree of protection and efficiency, resulting in better mileage, longer drain intervals, and less wear.
