Superplates are manufactured from a super-strong material with a 90,000 lbs. tensile strength and 80,000 lbs. yield strength to withstand thousands of cycles. Superplates are laser machined to avoid the heat and stress stamping inflicts on them. The crank bolt holes are bored in position to exacting tolerances in both size and location on CNC machines. The Superplate uses the "grip length" of the 6 or 8 crank bolts as dowels to prevent the plate from moving under high torque conditions.Unlike "billet plates" that violate the "flex principle" of a flexplate, the Superplate flexes like OEM plates are designed to do, absorbing the numerous machining tolerances that exist in our "non exact" world
