Founded in 1966 by Hank Manley, their initially product lines included stainless valves, forged pistons, camshafts, lifters, vanadium valve springs, push rods and timing chain kits. Following acceptance from leading race teams of the time, Manley soon found itself growing in size and product lines, this included manufacturing space doubling. Connecting rods were now manufactured in the plant along with a line of Platinum Series forged pistons.

Fast forward to 2002, Manley entered the high performance passenger car market as an OEM supplier of connecting rods for the 2003/2004 Ford SVT Mustang Cobra. Production reached 2500 rods per week without missing a single delivery date. Ford awarded Manley it's highest ever supplier rating. Manley's presence in the OEM market continued as a supplier for the Ford GT.

Today, Manley Performance continues to re-define itself in a high performance aftermarket industry that is constantly evolving. We've developed new products for growing markets such as sport compact, Ford modular and Chevy LS; as well as maintained our leadership role with the traditional V-8 engine business.
