About this part

Product Details

If you're building a high-performance engine for your Subaru BRZ or Scion FR-S with the 2.0L turbo, you're going to need strong connecting rods. These Pro Series I-Beam connecting rods from Manley are built to handle the extra stress that comes with boosted performance.

Manley makes these rods from a forged 4340 vacuum degassed steel alloy, which is a well-built material known for its strength and reliability under high loads. This means they can take the punishment of increased cylinder pressures and RPMs. They also offer different weight options, so you can match the rod to the specific needs of your engine build, whether you're aiming for a lighter rotating assembly or need something a bit heavier for balance.

These rods are sold individually, so you can buy exactly what you need for your project. Keep in mind that when you're upgrading connecting rods, it's always a good idea to check the manufacturer's installation instructions for proper torque specifications and any other hardware requirements.
