Recommended for SAE 250 or where SAE 140 does not provide adequate protection Alternative to Red Line Heavy ShockProof® on Nitro Drag Race vehicles with problems Can be used on Model A, Model T vehicles and antique/classic cars requiring 600W. Reduces noise levels in Morgan 3 Wheeler beveling boxes Excellent for off-road use where SAE 250 is required These products contain the extreme pressure additives necessary for maximum protection of road and racing cars, as well as friction modifiers (except NS) for proper limited slip operation.
Fully synthetic formulations created from polyol ester bases offer excellent lubrication under extreme conditions. Ester bases and friction modifiers (except NS) provide additional slipperiness for lower operating temperatures by reducing sliding friction in hypoid gears. High viscosity index (VI) to provide relatively constant viscosity and film thickness with variable temperature changes Superior shear stability and reduced oxidation compared to other synthetic and conventional gear oils. Exceeds API GL-5 specifications Designed to provide the highest degree of protection and improved differential efficiency for better mileage, longer drain intervals and less wear.
