About this part

Product Details

If you're building a high-performance Subaru EJ205 or EJ257 engine, Manley's Turbo Tuff Pro Series I-Beam Connecting Rods are a solid choice. These rods are built to handle the stresses of boosted applications, offering a significant upgrade over stock components. They are specifically designed for Subaru's popular EJ series engines, ensuring a proper fit for your build.

Manley offers these rods in your choice of either forged 4340 vacuum degassed steel or the even stronger 300M vacuum degassed steel alloy. Both materials are well-known for their strength and ability to withstand high cylinder pressures and RPMs. The I-beam design is a popular choice for performance applications because it offers a good balance of strength and weight. Some specific part numbers in the Pro Series line are also NHRA Legal, which is a notable detail if you're building for specific racing classes.

You can also select from different weight options, like Tour Lites, Lightweights, Standard, or Heavy Weights, to best match your engine's specific needs and intended use. These rods are a critical component for anyone looking to push their Subaru engine beyond its factory limits.
