GP-1 80w90 Gear Oil Case 12 x 1 Quart

The GP-1 80W90 Gear Oil Case containing 12 one-quart bottles is designed for automotive enthusiasts and mechanics who work on high-performance drivetrains, differentials, and manual transmissions. This gear oil is ideal for maintaining modified trucks, sports cars, and vintage builds, providing the necessary viscosity and thermal stability for extreme load environments.

Engineered to withstand shock loads common in limited-slip differentials and heavily modified powertrains, the 80W90 gear oil ensures cold-start pumpability in winter climates and maintains film strength under high-speed and high-torque operation. The formulation includes phosphorus and zinc anti-wear additives that protect gear tooth flanks and bearing surfaces from wear and damage.

This case is particularly beneficial for fleet maintenance of various vehicle types, including Ford 9-inch differentials and GM 12-bolt rearends. The bulk format of 12 one-quart bottles ensures you have enough supply for multiple vehicles or repeated service intervals without the need for constant restocking.
