Manley Valve Spring Retainers | Locks | Buckets

Led by GM Michael Tokarchik, in 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 its 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. They have developed new products for growing markets such as sport compact, Ford modular and Chevy LS; as well as maintained their leadership role with the traditional V8 engine business.
