EMPI 4140 Chromoly Crankshafts

The heart of any hi-performance engine is the crankshaft. Counter-weighted crankshafts greatly reduce power robbing and damaging crank- ex, 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.
