Yukon Gear 11.5in Chrysler & GM Helical Gear Type Positraction
Yukon Gear part YP PC11.5-HELIC is a gear-type helical limited-slip differential for the 11.5in Chrysler and GM differentials. Yukon's helical limited-slip units use floating helical-cut worm gears that lock torque down when acceleration or wheel slippage occurs, transferring power to the tire with the best traction in a smooth, progressive manner.
Key Features
- Helical gear-type limited-slip design
- Smooth, progressive torque transfer for improved traction
- Engages automatically under acceleration or wheel slippage
- Fits the 11.5in Chrysler and GM differential
Fitment
Fits vehicles equipped with the 11.5in Chrysler or GM differential. Confirm your exact differential before ordering.

FAQ
How does a helical gear-type limited slip work?It uses floating helical-cut worm gears that progressively transfer torque to the tire with traction as slippage is detected, rather than a hard mechanical lock.
What differential does this unit fit?This unit fits the 11.5in Chrysler and GM differentials.
How is this different from a locker?A helical limited slip provides smooth, progressive torque transfer for street-friendly performance, while a locker provides an abrupt 100% mechanical lock.
Is professional installation recommended?Yes. Installing a limited-slip unit requires differential disassembly and precise setup, and should be performed by a qualified technician.
Is this unit good for daily driving?Yes, the smooth engagement of a helical gear-type limited slip makes it well suited for daily street driving.
Does this include a ring and pinion gear set?No, this listing is for the limited-slip unit only; gears should be ordered separately if needed.
Can this be used for towing applications?Yes, this unit is well suited to heavy-duty towing applications on 11.5in Chrysler/GM differentials.
Do I need to confirm fitment before ordering?Yes. Confirm your exact differential before ordering.
Installation Instructions
- Remove the differential cover and carrier assembly.
- Remove the factory open differential or worn unit.
- Install the new helical limited-slip unit into the carrier housing.
- Reassemble the carrier and torque all fasteners to specification.
