Manley Performance Products has been around since 1966. With over 40 years of experience in performance engine components, they are at the leading edge of quality and performance. With only a few years in the sport compact market, Manley Performance has been developing performance engine products like Manley Rods, Manley Valves, Manley Valve Springs, Manley Titanium Retainers and more.
Today, Manley Performance continues to re-define itself in a high performance aftermarket industry that is constantly evolving. They've 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 V-8 engine business.
