Heavy SHOCKPROOF® Gear Oil

Heavy SHOCKPROOF® Gear Oil offers exceptional protection for heavily-loaded racing differentials and transmissions, as well as problem gearboxes. With a film thickness greater than SAE 75W250 and low fluid friction comparable to 75W90, it delivers superior performance in demanding applications.

• Ideal for racing and specialty applications, including Sprint, Midget, Dirt Late Model, Quick Change Differentials, Detroit Lockers, spools, NHRA Top Fuel, and Funny Car rear ends
• Fully-synthetic formula based on polyol ester base stocks for excellent lubrication under extreme conditions
• Contains extreme pressure additives for ultimate protection, and friction modifiers (except NS) for proper limited-slip operation
• Ester base stocks and friction modifiers (except NS) reduce sliding friction in hypoid gears, lowering operating temperatures
• High viscosity index ensures consistent viscosity and film thickness across varying temperatures
• Superior shear stability and oxidation resistance compared to other synthetics and conventional gear oils
• Exceeds API GL-5 specifications
• Engineered to maximize differential efficiency, extend drain intervals, and minimize wear
• Not recommended for most synchronized transmissions due to extreme slipperiness
