Red Line’s ShockProof Gear Oil features a unique lubricant containing a suspension of solid microscopic particles as an extreme pressure agent–unique solid dispersion which cushions gear teeth to help prevent tooth breakage and allows the use of lower viscosities.

Acting like a liquid grease, the viscosity characteristics of ShockProof Gear Oil allow the lubricants to resist throw-off and provide the protection of a greater film thickness with relatively light fluid viscosity, offering a “best of both worlds” balance of low drag and superior protection.

ShockProof Gear Oil products work in a variety of differential and transmissions, however, should not be used with pumps, filters, and with small lines–these fluids are designed wet sump or splash type lubrication.

The Red Line Heavy Weight ShockProof Gear Oil is recommended for heavily-loaded racing differentials and transmissions, Off Road racing and problem gearboxes. The viscosity characteristics allow the lubricant to resist throw-off and provide a film thickness similar to a 75W250 grade, while providing the same low fluid friction as an SAE 75W90.
