Heavy ShockProof Gear Oil - Choose Size

Red Line® Heavy ShockProof Gear Oil contains 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. High viscosity-index (VI) provides relatively constant viscosity and film thickness with varying temperature change. Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear. Can be used with pumps and coolers when equipped with an inline screen rather than a fine filter. Avoid pumping down the center of a main shaft as the unique particles could centrifuge out of solution.

• Film thickness greater than an SAE 75W250, yet low fluid friction like 75W90
• For heavily-loaded racing differentials and transmissions, problem gearboxes
• Most popular ShockProof product, many racing and specialty applications
• Exceeds API GL-5 specifications
• Better mileage, longer drain intervals, and less wear
• Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils
• Wide range of performance racing applications like Sprint, Midget, Dirt Late Model and Quick Change Differentials
• Also designed for 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
• Lowers operating temperatures by reducing the sliding friction in hypoid gears
• Relatively low viscosity, yet cushions gear teeth under extreme pressure
• Helps to prevent tooth breakage, resists throw-off
  
• Designed for wet sump transmissions and differentials with splash lubrication
