What material are these connecting rods made from?

These Manley connecting rods are forged from a strong vacuum-degassed steel alloy, selected for its durability and performance under high stress. They are designed to withstand the rigors of performance engine builds.

What is the significance of the ARP 625+ bolts included with this set?

ARP 625+ bolts are a high-strength fastener known for their superior tensile strength and resistance to fatigue, especially in demanding, high-heat applications. They are a significant upgrade over standard rod bolts and ensure a more secure connection.

What is the benefit of the I-beam design for connecting rods?

The I-beam design is a popular choice for connecting rods because it provides an excellent strength-to-weight ratio. This means the rods are strong enough to handle significant forces while remaining relatively lightweight, which is beneficial for engine performance and responsiveness.

About this part

Product Details

Manley Performance has a long history of building strong engine components, and their Turbo Tuff Pro Series I-Beam connecting rods are a prime example of that dedication. These rods are specifically made for Subaru EJ205 and EJ257 engines, commonly found in WRX and STI models, and are designed to handle the demands of boosted applications. They are a critical part of rebuilding or upgrading your engine's rotating assembly, ensuring reliable power delivery.

These connecting rods are forged from a strong vacuum-degassed steel alloy, chosen for its excellent durability under high stress. The I-beam design is a well-known shape for connecting rods because it offers a great balance of strength and weight savings, which is crucial for engine performance. This particular set comes with ARP 625+ bolts, which are a step up from standard hardware and are known for their high tensile strength and reliability, especially in high-performance and high-heat environments. The 5.216-inch length is a common upgrade size that can affect piston speed and compression ratios, so it's important to ensure it's compatible with your specific build.

When you're building a performance Subaru engine, the connecting rods are one of the most important parts to get right. These Manley rods, paired with ARP hardware, offer a solid foundation for a powerful and reliable engine. Make sure to consult your engine builder or a trusted mechanic to confirm compatibility with your specific build plans, including piston and crankshaft specifications.
