Yukon Gear 11.5in Chrysler & GM Helical Gear Type Positraction

Yukon's Helical Gear Type Positraction unit for 11.5-inch ring gears uses floating helical-cut worm gears. This design is key to how it transfers torque smoothly and progressively. When you accelerate or a wheel starts to slip, these gears engage to lock down torque, sending power to the tire that still has grip. It's a smart way to keep your truck moving forward, especially when traction is uneven.

What sets this unit apart is its reliance on gear teeth, not clutch packs, to manage torque. This means you get a high-performance limited-slip differential that's also low-maintenance. There are no clutch discs to wear out and replace, which is a common service item on other types of limited-slip units. This makes it a solid choice for drivers who want reliable traction without constant upkeep. It's built for 30-spline axles and fits a wide range of heavy-duty Chevrolet, GMC, Dodge, and Ram trucks from the early 2000s through recent models.

Installing this unit is a significant upgrade for your drivetrain. It's designed to work with the 11.5-inch ring gear found in many popular GM and Chrysler applications, including models like the Chevrolet Silverado 2500 HD, GMC Sierra 3500 HD, and Dodge Ram 2500. Make sure to consult your vehicle's service manual or a professional mechanic for specific installation procedures and any additional components you might need for a complete setup.
