What material are these Manley connecting rods made from?

These Manley Pro Series connecting rods are made from vacuum degassed 4340 steel alloy. This is a well-built material chosen for its strength and durability under high stress and temperature conditions common in performance engines.

What is the significance of the ARP 625+ cap screws?

ARP 625+ cap screws are a high-strength fastener designed to provide superior clamping force compared to standard bolts. They ensure the connecting rod caps remain securely attached, which is critical for engine reliability under high performance loads.

Are these rods suitable for a supercharged or turbocharged engine?

Yes, the robust construction from 4340 steel alloy and the inclusion of ARP 625+ cap screws make these rods a strong choice for boosted applications like supercharged or turbocharged engines. They are built to handle the increased cylinder pressures associated with forced induction.

About this part

Product Details

If you're building a high-performance Ford 4.6L Modular or 5.0L V-8 engine, you need connecting rods that can handle the stress. This set of eight Pro Series I-Beam connecting rods from Manley Performance is designed for just that. They are built with a strong I-beam design, a popular choice for many performance applications because it offers a good balance of strength and weight. These rods feature a 22mm wrist pin bore and come equipped with ARP 625+ cap screws, which are a significant upgrade for ensuring the connecting rod caps stay securely in place under extreme cylinder pressures.

Manley uses vacuum degassed 4340 steel alloy for these rods, a well-built material known for its toughness and ability to withstand high loads and temperatures. This makes them a solid option for boosted or high-revving engines where stock components might fail. The Pro Series line is also known for its precision machining, meaning these rods will fit right into your build without issues. While these specific rods are a standard weight, Manley offers other variations in their Pro Series line to suit different engine builds and performance goals.

This set includes eight connecting rods and the necessary ARP 625+ cap screws, ready for installation. It's important to note that when installing performance connecting rods like these, you'll want to ensure your crankshaft journals are properly prepped and that you use the correct assembly lubricants. For racing applications, some Manley Pro Series rods carry NHRA Legal certification, which can be important if you plan to compete in certain classes.
