Description

Replacement black steel 1600AX or 2300AX JB Performance supercharger dual offset 6 rib, 4 bolt pulley. Fits Lysholm style Whipple Supercharger kits only.

Made to the sizing specifications as the original for proper centering and less vibration. We use the correct cutting tools for proper belt grip. We also choose steel as it will wear less and cause less belt slip. This will be the last pulley you will ever need!

2.5″ smallest possible without issues.

This Whipple supercharger pulley is commonly used by on many engines that use the Lysholm AX compressor. This pulley design is a Whipple offset. We cannot confirm offset for other brands using a Lysholm compressor. Please note that some passenger side GM mounted compressors can use an AXO or AXM compressor as well as an AX. We carry these pulleys as well.

Please note that modified engines will see different results as well as if the crank pulley has been swapped to a different size. Increase in boost will depend on engine modifications and crank pulley size.
