Product Features

Introducing ATHENA ProSlip LS Extreme Pressure Gear Oil, specially formulated for use in limited slip differentials. Traditional multipurpose gear oils often fall short in addressing the unique requirements of limited slip differentials, leading to issues like chatter and slip-stick operation of clutches. However, ATHENA ProSlip LS is here to redefine performance and reliability.

 Key Features & Benefits:
  • Reduced Whining and Chattering: ATHENA PROGEAR LS 85W-140 (G127) effectively minimizes unwanted noise and vibrations, resulting in a smoother and quieter driving experience. By reducing whining and chattering, this lubricant enhances overall comfort and enjoyment during high-performance driving.
  • Excellent High Temperature Stability: Engineered to withstand the rigors of high-speed driving and intense operating conditions, this lubricant offers exceptional high-temperature stability. Its advanced formulation maintains viscosity and lubricating properties even under extreme heat, ensuring consistent performance and protection for your limited slip differential.
  • Smooth Clutch Operation: ATHENA PROGEAR LS 85W-140 (G127) ensures that clutches within limited slip differentials slide smoothly and engage seamlessly. This promotes precise and responsive handling, allowing you to confidently tackle corners and challenging terrain with ease.
  • Extreme Pressure Properties: Built with top-performance extreme pressure additives, this lubricant provides unmatched protection against metal-to-metal contact and wear under heavy loads. Its extreme pressure properties ensure the durability and longevity of gears and components, even in the most demanding driving conditions.
