Red Line Synthetic Oil Heavy ShockProof Gear Oil is a fully synthetic differential lubricant formulated for demanding automotive and performance applications. Supplied in a 1-gallon container, this heavy-duty gear oil uses polyol ester base stocks to provide reliable lubrication under extreme pressure, temperature, and load conditions. Manufacturer part number 58205 and vendor part number 58205 identify this product for ordering and application reference.
Designed for hypoid gears and differentials, the formula combines ester base stocks and friction modifiers to reduce sliding friction and help lower operating temperatures. Its high viscosity index helps maintain a more consistent viscosity and protective film across changing temperatures, supporting dependable gear protection during both cold starts and sustained high-load operation. The formulation is intended for applications requiring a robust gear lubricant that can help improve differential efficiency and reduce wear.
