RED LINE Gear Oil 75w-140 GL-5

Red Line 75w-140 high performance gear oil is specially designed to provide the highest degree of protection and improved differential efficiency. Red Line 75w-140 contains polyol ester base stocks, which provides excellent lubrication even under extreme loads and temperatures. Additives used in most synthetics can decompose at elevated temperatures, forming deposits which can seize bearings and wear seals, this oil is design from base stock up not to.

This oil has fantastic low oil temperature flow that ensures adequate bearing lubrication at temperatures as low as -40F and can provide 10% increases efficiency during warm up.

The extreme slipperiness of this lubricant helps prevent limited slip chatter and reduces differential temps 10F – 70F in heavy duty use.
