Protect your drivetrain and unleash more power with Royal Purple Max-Gear 75W-90 Synthetic Gear Oil (P/N: 1300), available in a 1-quart bottle at Straight Six Imports. This is the ultimate upgrade for heavily loaded differentials, transfer cases, and manual transmissions in your performance import.

Max-Gear is an ultra-tough, API GL-4 and GL-5 rated hypoid gear oil formulated with Royal Purple's proprietary Synerlec® additive technology. This combination provides the highest possible film strength, which dramatically reduces friction and wear even under extreme pressures—a common scenario in aggressive driving or track use. By reducing friction, Max-Gear allows gears to run cooler, quieter, and smoother, directly increasing power throughput to the wheels.

Key Performance Benefits for Drivetrains:

• Maximum Wear Protection: Synerlec technology provides unsurpassed film strength, extending the life of gears and bearings.

• Includes LSD Friction Modifier: Pre-formulated for Limited-Slip Differentials (LSDs) and locking differentials; no additional additive is required.

• Temperature Reduction: Lowers operating temperatures in the gearbox and differential compared to conventional and standard synthetic oils.

• Non-Corrosive: Safe for use in manual transmissions containing "yellow metals" (brass/bronze) synchronizers, where a GL-4/GL-5 fluid is specified.

• Viscosity: 75W-90 provides an excellent balance of cold-weather fluidity and high-temperature protection.
