They offer heat-treated, precision machined gear teeth for added strength and feature low runout values to produce an incredibly durable flexplate. They all come with a SFI 29.2 explosion-proof rating. Specifications: Concentric machined to .005". One piece design - 100% machined. Chamfered gear tooth provides better engagement.
