Cranks are then magna fluxed, shot peened and all journals are nitrided, precision ground and micro polished. Additional features include cross drilled, chamfered oil holes, dynamic balancing, 8 dowel and extra long 8mm dowel pins. Choose the journal size and stroker combination that best suits your application.

Note: Stroker Cranks require machining of case and possibly other internal components, for rod clearance.

EMPI 4140 Chromoly Crankshafts
The heart of any hi-performance engine is the crankshaft. Counter-weighted crankshafts greatly reduce power robbing and damaging crank-flex, high RPM harmonics and vibration through the entire power range. EMPI's Counter-weighted Crankshafts are perfect for the racer on a budget. These cranks are precision ground, micro-polished, nitrided and balanced. Features include: forged from 4140 chromoly, radiused standard/standard journals, chamfered oil holes, 8 dowel, 8mm dowel pins and cross-drilled. Available in stock 69mm stroke or 74mm stroker versions. Both use stock VW main and rod bearings.

NEW DIRECT DRILLED CRANKSHAFT
In cross-drilled crankshafts the pressure is divided in two directions, creating a zone of turbulence causing effects similar to oil foaming that reduces constant lubrication. DIRECT DRILLED Crankshafts force the oil in one direction for better full flow lubrication. These cast Cranks are New Standard/Standard with stock 69mm stroke.
