Yukon Gear & Axle YP PC11.5-HELIC: Performance Differential for Your Truck
If you're looking to enhance the traction and performance of your truck, the Yukon Gear & Axle YP PC11.5-HELIC is a top choice. This helical limited-slip differential is designed specifically for GM and Chrysler 11.5" axles, making it an ideal upgrade for owners of popular models like the Chevrolet Silverado and GMC Sierra. With its advanced design, this differential ensures that power is distributed effectively, allowing you to tackle tough terrains with confidence.
How It Works
The YP PC11.5-HELIC utilizes floating helical-cut worm gears that engage seamlessly when acceleration or wheel slippage occurs. This means that torque is transferred to the tire with the best traction, ensuring a smooth and progressive response. Unlike traditional clutch-pack differentials, this unit relies on gear teeth to transfer torque, resulting in lower maintenance and no clutch discs that need replacement over time.
