Yukon Gear & Axle YP PC11.8-HELIC-16B Performance Chrysler 11.8in AAM Helical Gear Positraction 2016+ 16-Bolt

The Yukon Gear & Axle YP PC11.8-HELIC-16B is a helical gear Positraction limited-slip differential designed for the Chrysler/AAM 11.8-inch rear axle found in 2016 and newer heavy-duty Ram trucks. Unlike traditional clutch-pack limited-slip differentials that require friction modifier additives and periodic rebuilding, this unit uses precision-cut helical gears to deliver smooth, consistent torque biasing with no maintenance requirements.

Key Features:

• Designed specifically for the Chrysler AAM 11.8-inch rear axle with the 16-bolt cover pattern (2016 and newer)
• Helical gear design provides torque-sensing, automatic limited-slip action without clutch packs or springs
• No friction modifier additives required — compatible with standard gear oil
• Maintenance-free operation with no rebuild intervals
• Delivers improved traction under acceleration on both on-road and off-road surfaces
• Direct OEM-style fitment for straightforward installation
• Built to handle the increased power output of modern Ram 2500/3500 heavy-duty applications
• Manufactured by Yukon Gear & Axle, a trusted name in differential and drivetrain components

The helical gear Positraction design is ideal for towing, hauling, and off-road use where predictable and reliable traction control is essential. Because torque transfer is gear-driven rather than friction-dependent, performance remains consistent over the life of the differential without the fade or wear associated with clutch-type units.
