The 6-bolt, 6-pin flange eliminates flywheel-to-crank movement that costs power and durability at high RPM.

A forged 4340 chromoly crank, properly nitrided and balanced, is the foundation for any engine making real power. The Chevy journal allows use of a far wider range of high-end aftermarket rods (Carrillo, Eagle, Manley, Scat, etc.) than the OEM VW journal sizes permit — cost-effective compared to building around custom VW-journal rods.\u003c\/p\u003e\u003ch3\u003eStroke options\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e78mm\u003c\/strong\u003e — B4-0002-5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e82mm\u003c\/strong\u003e — B4-0003-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e84mm\u003c\/strong\u003e — B4-0002-6 (big-stroke option)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMaterial: 4340 chromoly forged\u003c\/li\u003e\n\u003cli\u003eMain journals: Nitrided, Type-IV\u003c\/li\u003e\n\u003cli\u003eRod journals: Chevy (2.000\")\u003c\/li\u003e\n\u003cli\u003eFlywheel flange: 6-bolt, 6-pin\u003c\/li\u003e\n\u003cli\u003eSold as: Each\u003c\/li\u003e\n\u003cli\u003eWeight: ~24 lb (shipping)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAbout BUGPACK\u003c\/h3\u003e\u003cp\u003eBUGPACK is EMPI's high-performance engine and chassis line for the air-cooled VW community.
