Gear Oils & Differential Fluids

Gear oils lubricate the gears, bearings, and synchronizers in manual transmissions, differentials, transfer cases, and transaxles. The correct gear oil weight and specification protects against wear, reduces operating temperatures, and ensures smooth shifting. Performance and racing gear oils offer enhanced film strength for high-torque applications and aggressive driving.

OneFastShop carries gear oils including 75W-90, 75W-140, 80W-90, and 85W-140 gear oils, limited-slip differential additives, manual transmission fluids, transfer case fluids, synthetic and conventional gear lubricants, and racing-grade gear oils for cars, trucks, SUVs, and performance applications.

Every gear oil at OneFastShop ships brand-new and factory-sealed. Whether you're servicing a differential, filling a rebuilt transmission, or upgrading to a racing-grade gear lubricant, OneFastShop has the right gear oil. Shop the full gear oils collection today.
