Compact Bugpack 86mm Forged 4340 Chromoly Counterweighted Crankshaft, Chevy Journals In Multiple Colors [QsjPNMe2]

86mm Stroke Counter-weighted Crankshaft, Chevy Journals

Bugpack has developed this high quality counter-weighted Stroker Crank with the serious racer in mind. Multiple die stamp forged from 4340 chromoly (One of the strongest materials available for crankshafts). Cranks are then magna fluxed, shot peened and all journals are nitrided, precision ground and micro polished. Additional features include dynamic balancing, drilled to 8 dowel and 8mm dowel pins are installed.

Some builders prefer using a crankshaft with Chevy rod journals, rather than stock VW ones.  The Chevy journals are 2", so they are slightly smaller diameter than stock VW.  This provides for less reciprocating weight. It also offers better clearance when using a large stroke, so it's less likely to make contact with the case and/or camshaft.  Since the bearing surfaces are smaller, they also have less friction, or bearing drag, so they provide better power.
