Yukon Gear & Axle YP PC11.5-HELIC Helical Limited Slip Differential for 11.5" Chrysler/GM

The Yukon Gear & Axle YP PC11.5-HELIC is a helical gear-type limited-slip differential designed for 11.5-inch Chrysler and GM axles. This precision-engineered LSD provides superior traction and power distribution to both wheels, making it ideal for performance street applications, off-road use, and vehicles that demand reliable traction in varying conditions.

How It Works:

In its static state, this limited-slip differential is pre-loaded to provide traction to both wheels simultaneously. When the LSD encounters additional loading—whether under hard acceleration, aggressive cornering, or when wheel slippage occurs off-road—the internal clutch packs actively limit wheel spin across the drive axle. The system permits the axle shafts to rotate at different speeds while continuously balancing torque application between the two axles, effectively transferring more power to the wheel with the best available traction.

Key Features:

• Helical gear design ensures smooth, transparent engagement with quiet operation
• Forged 8620 steel case construction for maximum strength and durability
• High-strength alloy internal components built for long service life
• Maintenance-free operation—no periodic service required
• Pre-loaded design provides immediate traction response
• Compatible with 11.5-inch Chrysler and GM rear axle assemblies

This helical-style limited-slip differential offers a significant upgrade over open differentials, delivering improved acceleration, enhanced cornering stability, and better off-road capability without the harshness or noise associated with traditional clutch-type or locking differentials.
