It suits high-power street, drag and circuit builds where the factory crank's harmonics and strength become a problem.\u003c\/p\u003e\n\u003cp\u003eChoose the stroke: 85 mm keeps the standard 3.0L capacity, while 90 mm takes the engine to 3.2L with matching stroker pistons. Both keep factory-width journals and use tear-drop cross-drilled oiling.\u003c\/p\u003e\n\u003cp\u003eThe crank is machined from double-melted 4340 true billet bar rather than a forging, which helps it resist flex and run with much lower harmonics than a factory crank.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Installation by a professional is recommended.
