EMPI 69mm 4140 Forged Counterweighted Crankshaft, VW JournalsThese 69mm crankshafts are built for both power and longevity. A forged 4140 chromoly counterweighted crank is far superior to a cast crank and the counterweights minimize vibration and flexing, commonly associated with stock cranks revving past 5000 RPM's. It's stronger, will not break, and can be machined for your next build, if needed. Ours are balanced, micro polished, and nitrided for superior longevity and performance. Uses stock VW main and rod
