Yukon Gear AAM 11.8 Helical LSD 2016+ Ram 3500 16-Bolt - YP PC11.8-HELIC-16B

Helical Limited-Slip Differential, AAM 11.8-Inch, 2016-Up Ram 3500, 30-Spline, 16-Bolt Ring Gear, Full-Floating, Assembled

Yukon Gear YP PC11.8-HELIC-16B is a complete helical gear limited-slip differential for 2016-up Chrysler/Ram applications using the AAM 11.8-inch full-floating rear axle with a 16-bolt ring gear. This assembled steel carrier accepts 30-spline axle shafts and is compatible with all listed gear ratios.

Instead of using replaceable clutch packs, this limited-slip differential uses floating helical-cut gears to bias torque across the drive axle. When acceleration or wheel-speed differences load the differential, the gear-driven design transfers torque between the axle shafts while still allowing the wheels to rotate at different speeds.

The unit includes the differential case and is supplied assembled for compatible AAM 11.8-inch applications. Its clutch-free internal design eliminates clutch discs as a wear component, making it a gear-driven limited-slip option for Ram 3500 rear axle builds using the correct 16-bolt carrier configuration.

About Yukon Gear Helical Limited-Slip Differentials:

Yukon Gear helical limited-slip differentials use gear-driven torque biasing rather than clutch packs. Helical-cut internal gears respond to torque load and wheel-speed differences while permitting normal differentiation between the axle shafts. Because the design does not depend on friction clutch discs, there are no clutch packs to periodically replace as part of normal carrier service.
