RTS’ full billet steel flexplates are for the serious racers. They are machined out of cold-drawn AISI 1045 carbon steel and come with a stealth black oxidised plating for added durability. Their strength to weight ratio is incredible compared to their 2-piece counterparts which enables them to handle extreme engine builds in excess of 1000 HP. 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.
