What makes H-beam connecting rods a good choice for performance engines?

H-beam connecting rods, like these from Manley, are known for their strength and rigidity. This design helps them withstand the higher pressures and stresses found in performance or boosted engines, offering a solid foundation for your build.

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

ARP 625 bolts are a step up in strength and fatigue resistance compared to standard ARP 8740 or ARP 2000 bolts. They are well-suited for high-output applications where extreme reliability and durability are crucial.

Are these connecting rods a direct replacement for stock Subaru rods?

These Manley connecting rods are designed to be a direct replacement in terms of length and journal size for many Subaru EJ20 and EJ25 engines. However, it's always recommended to consult your vehicle's service manual and verify all specifications before installation.

About this part

Product Details

If you're building a performance Subaru EJ20 or EJ25 engine, you need connecting rods that can handle the extra stress. This set of Manley H Tuff Plus connecting rods is built for just that. They're a well-built H-beam design, which is a popular choice for boosted applications because of its strength and rigidity. Manley makes these to the same high standards as their more expensive Pro Series rods, so you know you're getting a solid part.

What sets these apart is the attention to detail in their construction. Manley finishes them to very precise tolerances, ensuring that each rod is nearly identical. This means better balance and smoother operation for your engine. They're also available with your choice of ARP 8740 or ARP 2000 bolts, but this specific set comes with the stronger ARP 625 bolts, which are a great option for high-output builds. The 5.216-inch length is a common size for these Subaru engines, and they fit right in place of the stock rods.

When you're pushing an engine hard, the connecting rods are a critical component. These Manley rods are a popular choice because they offer a strong foundation for a performance build without breaking the bank. Make sure you have the right tools and a service manual for your specific Subaru model when it comes time for installation.
