The Eagle connecting rods for the WRX & STI undergo a 2-piece forging process in China and are then shipped to the US for final machining and testing; making for a cheaper rod that is durable and precise. Eagle's EJ20, EJ255, & EJ257 WRX & STI rods include ARP 3/8" 2000 rod bolts for extensive ability to handle power and boost. 5.137" rod length.

Manley Connecting Rods

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.

Carrillo Connecting Rods

If you are looking for connecting rods that can take whatever you can throw at them, look no further. Carrillo connecting rods are forged and use only the strongest materials to ensure they will hold massive amounts of power. They are run through a thorough inspection process once finished to ensure each rod is made to the highest quality standard. These rods are for enthusiasts that require the absolute best and will not compromise on quality.

Pro-A Beam Rods: The A-beam rod is a light weight rod that is designed for high revving motors. It can hold moderate horsepower numbers and is the rod of choice for most street cars looking to push more power than the stock internals can handle, they are rated for up to 650whp.

Pro-Super A Beam Rods: Carrillos's Pro-Super A beam (Pro-SA) rods are lighter than the traditional H-beam style rod, yet still unbelieveably strong. Pro-Super A beam rods bridge the gap between Pro-H and standard Pro-A rods, designed for use in mid to high horsepower and high boost turbocharged and supercharged applications. Pro-Super A beam rods allow for more horsepower and higher RPMs with the advantage of a reduced windage design. Pro-Super A beam rods for the WRX/STI ship with standard 3/8th inch WMC cap bolts and are rated to 800whp, they are great for cars that see both street and race driving.

Pro-H Beam Rods: The H-beam rod has become the industry standard design for high-performance applications. Considering the best overall performance of the part, combined with the least amount of weight, the H-beam is Carrillo's strongest, most durable design available. Carrillo H-beam rods are recommended for race applications where no compromise in performance is possible. Pro-H rods for the WRX/STI are available with 3/8th inch cap bolts in either standard WMC or Carrillo specific design which can be retorqued as many times as you want and will not need to be replaced. These rods are for 1000+whp race only machines and are not optimal for street use.
