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. Crankshafts, an expanded range of pistons and connecting rods, larger diameter pushrods as well as new valve and valve spring offerings are just a taste of what you’ll find in this catalog.
