What is the primary benefit of using ARP 625+ bolts with these connecting rods?

ARP 625+ bolts offer higher tensile strength and improved fatigue resistance compared to standard ARP bolts. This makes them ideal for high-performance engine builds that experience significant stress and require robust clamping force.

Are these connecting rods suitable for a stock engine rebuild?

While these rods are exceptionally well-built, they are primarily designed for performance and high-stress applications, especially with turbo upgrades. For a standard, stock rebuild, they may be more robust than necessary, but they will certainly provide excellent durability.

What other components are typically needed when installing new connecting rods?

When installing new connecting rods, it's crucial to have new rod bearings, piston rings, and often new main bearings. It's also recommended to have the crankshaft balanced and checked for straightness.

About this part

Product Details

Forged from vacuum degassed 4340 steel alloy, these Manley Turbo Tuff I-Beam connecting rods are built to handle serious power in your 2002-2012 Subaru Impreza WRX or STI. If you're pushing your EJ205 or EJ257 engine beyond stock limits, especially with a turbo upgrade, these rods are a critical component for reliability. They are designed to be a strong link between your pistons and crankshaft, ensuring efficient power transfer even under demanding conditions.

Manley's Pro Series rods are well-built and meticulously manufactured. This set comes with ARP 625+ bolts, which are a step up from standard ARP bolts, offering increased tensile strength and fatigue resistance. This means they can handle the higher clamping forces and stress associated with performance engine builds. The I-beam design is a popular choice for performance applications because it offers a good balance of strength and weight, making it suitable for a wide range of engine builds, from street performance to track use.

This set includes four connecting rods, enough for one complete engine. When rebuilding or modifying your Subaru's engine, using robust internal components like these Manley connecting rods is essential for long-term durability and performance. Always refer to the manufacturer's installation instructions for proper torque specifications and assembly procedures.
