75W90 Gear Oil 1 Quart

The 75W90 Gear Oil 1 Quart from REDLINE OIL is designed for high-performance differential and transmission applications that require exceptional film strength under extreme pressure and heat. This synthetic formulation is ideal for modified street machines, track-focused builds, and heavy-duty towing, ensuring optimal protection for gears during aggressive driving.

REDLINE's 75W90 Gear Oil utilizes advanced synthetic base stocks and extreme pressure additives that adhere to gear teeth, preventing metal-to-metal contact and wear. The 75-weight winter rating allows for easy cold-start pumpability, while the 90-weight summer rating maintains the necessary viscosity for high-load operations. This balanced viscosity profile resists breakdown from heat cycling, making it suitable for turbocharged applications and environments where temperatures exceed 200°F.

This gear oil is particularly beneficial for limited-slip differentials, helical gearsets, and performance manual transmissions found in modern sports cars, muscle cars, and modified trucks. Always consult your owner's manual or transmission builder's specification sheet, as most modern performance differentials and gearboxes either require or greatly benefit from this high-quality fluid.
