Description

Lunati Pro Series forged crankshafts are manufactured from the highest quality 4340 certified steel. The 4340 material meets all aircraft quality standards for material cleanliness and purity standards. Lunati Pro Series crankshafts are manufactured to exacting specifications and are held to strict tolerances. Design Specifications: #1 and #4 rod journals are drilled with lightening hole, which reduce the inertia weight of the crankshaft. All journal radii are ground to . 140". The roundness of each journal is . 0001" or less. Overall stroke is held to . 001". The surface finish of the shaft is a grade 5 RMS or better. Each shaft is heat treated by plasma gas nitrite, creating a case depth of . 015"-. 022". This heat treating creates high compressive loads, which in turn gives higher cycle bending fatigue. NOTE: All crankshafts must use chamfered bearings!
