Description

New Whipple Supercharger Jackshaft 175F 2.9L, for 14-18 GM DI Truck applications. This is the latest generation. This will fit G2, G3, and G4. Requires the front hub to be converted to the new style 20mm hub. Part number: W pulley hub keyed 20mm.

We recommend using a new hub and hardware with these shafts. These shafts are easily bent on a press from improper servicing procedures. They are also damaged from improper torque to the front pulley hub and from improper/excessive belt tension. Please note that a used hub will most likely result in failure of the shaft if the hub has any keyway wear. It should be a light tap fit.
