Clearance for Stroker Crank

Cranks larger than 74mm will require machine work on the case to make them fit. The larger the crank, the more work is required to make them fit.

A stroker crank is a great way to add not only horsepower, but torque to your air cooled VW engine.  The longer stroke on the crank gives the piston more leverage to apply radial force on the crank shaft.  That extra leverage means extra torque.  Extra torque means your car is much more fun to drive.  We will clearance your case for up to an 84mm crank, although we typically recommend sticking with an 82mm crank for street use.

Because each crank and rod combination is different, you may find there is minor work required to fit your crank and rods to your case after clearancing.  Please call us for assistance if you feel you need it.
