Yukon Gear 3 Qt. 80W90 Conventional Gear Oil with Positraction Additive

Optimize your limited-slip differential's performance with the Yukon Gear 3 Qt. 80W90 Conventional Gear Oil package, which includes a bottle of Yukon's specialized positraction additive. This kit combines a reliable conventional 80W90 gear oil with an effective friction modifier, designed to ensure smooth operation and reduce the common chatter associated with clutch-type limited-slip differentials.

Enhanced Performance for LSDs:

  • Conventional 80W90 Gear Oil: Provides robust lubrication for gears and bearings, suitable for a wide range of differential applications.
  • Yukon Positraction Additive: Specifically formulated to reduce noise and chatter in clutch-driven limited-slip differentials, ensuring smooth engagement during turns.
  • Combined Solution: This kit offers a convenient way to service differentials requiring both gear oil and a friction modifier, ensuring proper compatibility and performance.
  • Wear Protection: The gear oil component helps protect against wear, while the additive ensures the LSD operates as intended.
  • 3 Quart Capacity: Ideal for topping off or refilling many common differential applications.

This formulation is specifically recommended for vehicles equipped with limited-slip or positraction differentials. Using the correct gear oil and friction modifier is crucial for the longevity and proper function of these specialized units. The additive helps to modify the friction characteristics of the fluid, allowing the clutch plates within the LSD to slip and engage smoothly, thereby preventing chatter and improving traction.

Ensure your limited-slip differential performs at its best. Choose the Yukon Gear 3 Qt. 80W90 Conventional Gear Oil with Positraction Additive for reliable protection and smooth operation. Available now at GGCRACING.
