75w140 Pro Gear Oil Case 12x1 Quart

The 75w140 Pro Gear Oil Case by MAXIMA RACING OILS delivers premium synthetic lubrication for high-performance differential and transfer case applications. This case of 12 one-quart bottles is engineered for serious off-road enthusiasts, performance drivers, and mechanics who demand reliable gear protection under extreme loading conditions. Whether you're running a heavily modified truck, pushing a track-focused vehicle, or maintaining equipment in severe terrain, this professional-grade formulation ensures consistent viscosity and film strength when it matters most.

MAXIMA's 75W140 synthetic blend utilizes advanced additive chemistry to provide superior anti-wear protection, anti-corrosion resistance, and thermal stability across a wide temperature range. The 75-weight winter rating ensures cold-start pumpability, while the 140-weight summer rating maintains robust film strength under sustained high-torque stress—critical when running aggressive gearing ratios or towing heavy loads. This viscosity grade is particularly effective in limited-slip and locking differentials where extreme pressure lubricity and shear stability prevent gear scuffing and bearing wear during rapid acceleration, off-road articulation, or sustained highway cruising.

The case format makes this ideal for fleet maintenance, shops performing regular service intervals, or builders managing multiple vehicle projects. Mechanics and enthusiasts working with Dana, Ford 9-inch, GM 12-bolt, and other aftermarket differentials rely on this oil to extend component life and reduce noise in noisy gear sets. Check your vehicle's factory recommendations or consult with a shop specializing in your platform—most modern trucks, SUVs, and performance cars with standard or locker-equipped differentials benefit from a seasonal drain-and-fill with MAXIMA's proven formula.
