What is this part called?
1302 / 1303 Beetle IRS Helical LSD 33 to 37 Tooth Conversion Kit
What does this part do on a VW?
This conversion kit allows a Blackline helical limited-slip differential (SKU: 020050020) to be adapted from the earlier 33-tooth configuration to suit 37-tooth applications found in specific IRS Beetle transaxles. It provides the components required to correctly convert the differential for compatibility with later 37-tooth ring gear setups.
Designed for use in performance, motorsport, and high-powered street applications, this conversion kit enables the installation of a modern helical limited-slip differential into compatible Volkswagen IRS gearboxes. A helical LSD improves traction by automatically transferring torque to the wheel with the greatest grip, enhancing acceleration, cornering stability, and overall vehicle control without the maintenance requirements associated with clutch-type differentials.
