When your build's bottom end has to survive boost, nitrous or rpm, Manley's forged internals are the insurance policy that lets you tune with confidence.

Manley's Turbo Tuff rod series was engineered specifically for high-boost applications and has become a standard in four-digit-horsepower builds; the company has supplied NASCAR and NHRA engine programs for decades.

Manley Performance has been forging the guts of fast engines since March 1966, when Hank Manley opened shop at 13 Race Street in Bloomfield, New Jersey and put Don Garlits and Grumpy Jenkins on his first catalog covers. Six decades later the Lakewood, New Jersey plant runs 75 CNC spindles turning out stainless and titanium valves, forged pistons, cranks, and the H-beam and Turbo Tuff connecting rods trusted everywhere from NHRA nitro to 1,000 horsepower import builds, with OEM pedigree that includes factory rods for the SVT Mustang Cobra and the Ford GT. When your build absolutely cannot throw a rod, Manley is the name engine builders have reached for since the muscle car era, and the sport compact world runs on it today.
