Core Technical Specifications

  • Stroke Length: 82mm.

This crankshaft is primarily used to build custom, high-displacement "stroker" engines for classic Volkswagen platforms. Common vehicular applications include:

  • Custom VW Beetle / Bug drag racers and high-performance street cars.
  • Sand rails and dune buggies requiring extreme low-end torque.
  • Baja Bugs and off-road air-cooled race vehicles.

Why This Specific Configuration is Used

  • Flanged Flywheel Design: The 6-bolt, 6-pin flanged configuration eliminates the risk of "throwing" or losing a flywheel under extreme RPMs or heavy loads, which is a common failure point on standard 8-dowel VW cranks.
  • Chevy Rod Journals: Utilizing Chevy rod journals allows engine builders to use smaller, high-strength Chevrolet-style connecting rods. This offers better clearance inside the VW engine case, reducing the amount of internal machining required.
  • Type 4 Mains: Standard Type 1 cases are often machined to accept the larger Type 4 main bearings to improve the structural rigidity of the engine block's bottom end.
