COGENT GUARD HD SAE 85W-140 Heavy Duty Gear Oil API GL-5
COGENT GUARD HD 85W-140 GL-5 SERIES
Product Description:
COGENT GUARD HD 85W-140 GL-5 SERIES is a top-tier, high-viscosity heavy duty gear oil designed to deliver ultimate protection across highly stressed mechanical systems. Formulated from premium, highly stable base oils and integrated with a cutting-edge additive system, this high performance gear oil effectively shields drivetrain hardware operating under intense load variations. It is purpose-built to maintain fluid film integrity in automotive heavy-duty transmissions, drive axles, and final drives.
As a premium-grade extreme pressure gear oil, this formulation is specifically optimized for heavy-duty axles and final drive assemblies where extreme contact pressures and heavy shock loadings are regularly encountered. This stable composition provides reliable service as a dedicated differential gear oil and axle gear oil, preventing micro-pitting, gear tooth scuffing, and component wear under severe torque stresses. Ideal for mixed transport architectures, this commercial vehicle gear oil ensures optimal mechanical efficiency and fluid longevity across long-haul highway logistics and demanding industrial environments.
Features & Benefits:
• Exceptional thermal & oxidation stability protects against deposit formation and oil thickening, thus maintains the life and performance of lubricant and transmission.
• Outstanding anti-wear properties and excellent film strength provides exceptional equipment protection, that not only results in fewer breakdowns but also helps improve transmission efficiency.
• Excellent rust and corrosion protection for longer component life.
• Compatibility with seals and gaskets, leads to minimize oil leakage and reduced contamination.
Application :
• Suitable for use in all passenger cars, on-highway light and heavy-duty trucks, and commercial vehicles requiring an optimized 85W-140 gear oil.
• Ideal for heavy-duty manual transmissions, axles, and final drives requiring robust API GL-5 level performance characteristics.
• Highly recommended for applications across off-highway industries including construction, mining, quarrying, and agriculture.
• Designed for other heavy-duty industrial and automotive gear oil configurations involving hypoid gears operating under conditions where high-speed/shock load, high-speed/low-torque, and/or low-speed/high-torque settings exist.
