Red Line Oil #58204 Gear Lube, Shockproof Heavy Gear Oil, 75W90, Synthetic, 1 qt., Each. 

R31-58204

Description:

Red Line Gear Oils are designed to provide excellent low-temperature characteristics and improved gear protection at higher temperatures. Red Line Gear Oils will reduce differential temperatures 10-70 degrees F. Efficiency improvements between 1-5% are typical. The synthetic base stocks used have tremendous thermal stability and provide the best film strength available. The unique combination of base stocks and additives allow Red Line gear oils to carry higher loads compared to petroleum  lubricants.

Features:

*Film thickness greater than an SAE 75W250, yet low fluid friction like 75W90
*For heavily-loaded racing differentials and transmissions, problem gearboxes
*Many performance racing applications like Sprint/Midget/Dirt Late Model Differentials, 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
