Heavy SHOCKPROOF® Gear Oil

• Film thickness greater than an SAE 75W250 yet low fluid friction like 75W90
• For heavily-loaded racing differentials and transmissions problem gearboxes
• Most popular of the Shockproof products, for many racing and specialty applications
• Many performance racing applications like Sprint Midget Dirt Late Model and Quick Change Differentials Detroit Lockers and spools NHRA Top Fuel and Funny Car rear ends
• Not recommended for most synchro applications due to the product's extreme slipperiness

These products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers (except NS) for proper limited-slip operation

• Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions
• Ester base stocks and friction modifiers (except NS) provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
• High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change
• Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils
• Exceed API GL-5 specifications
• Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear
