A quality steel rod (not made in China) will last essentially a lifetime if kept within its design range. Not so with aluminum no matter what the alloy, or QA/QC. Its just the nature of the materials inherent poor fatigue resistance qualities.


Oliver and Manley offer very reasonably priced 100% USA material, USA forging, and USA machined rods... right around $1200 a set.

The only Manley connecting rod that is made in the USA is the Pro Beam. All the others are off shore blanks machined in the USA.
