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 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.
