The Ultimate ATB Diff for 4WD Syncro Vanagon. Transfer power to both wheels smoothly and automatically, without the use of friction discs or drive plates common in other limited-slip designs. The Weddle Industries Automatic Torque Biasing Differential for Syncro Vanagon features a strong helical gear driven design that offers greatly improved traction in a wide range of driving conditions.

Acting as an incredibly smooth limited slip differential during normal to moderate driving, this unit can be “locked up” in extreme duty situations. The locking feature utilizes the factory VW air locker controls providing the best of
 both worlds, the drivability of an ATB differential, with a full locker option when needed. While it is designed to be used in Syncro Vanagons equipped with factory locking differentials, it can be installed in non-locker equipped Syncro’s and 2WD Vanagons with additional parts.

ATB diffs are known for their extreme durability, with no costly plates or clutches to wear out. All internal components are made from the highest quality materials and critical housing dimensions are precision ground after heat treat.
