Manley has been in business since 1966 producing aftermarket and OEM engine internals, supplying such cars as the Ford GT. Manley’s premier connecting rod series is the Turbo Tuff line which was designed to be the best money can buy. Manley Performance is synonymous with winning and their products power some of the fastest cars around.
Manley H-Beam rods are a lower cost alternative to the Turbo Tuff series, they are partially produced in China and then finished in the US to reduce costs but retain quality. These rods are an excellent alternative to Eagle rods, both of which should be considered when buying either one. Manley H Beam rods are weight matched within +/- 1.5 grams of each other and both ends of the rod are rounded perfectly. These are the perfect rods for street applications pushing up to 600 wheel horsepower.
Manley Turbo Tuff I Beam Rods are made using forged 4340 aircraft quality vacuum degassed material. Manley Turbo Tuff rods are machined in house, in the USA, to ensure the highest quality product. Each rod is shot-peened after machining and magnafluxed. The bores are round with no taper and these rods use APR 2000 cap screws for ultimate strength.
Pro series rods are the strongest rod manley offers and are also made of 4340 aircraft quality material. They are fully machined to produce the lightest rod with the most holding power possible. These rods are designed to be used with cars making 1300+ horsepower. They are shot peened and 100% magnafluxed and use 3/8″ ARP 2000 cap fasteners.
