STEEL CONNECTING RODS

Manley 4340 Steel 'H' beam & 'I' beam Connecting Rods

Manley Performance
Steel Connecting Rods

...Often Copied, But Never Duplicated!!!

H-Beam Series










Don’t be fooled; not all H-Beams are created equal. Manley H-Beams are not
only very “economically” priced, but they are finished to the same exacting
tolerances and high quality standards as our Sportsmaster® and Pro Series rods.
Final hone size, thread detail, bend and twist - these are attributes we take
very seriously. You will find the Manley H-Beam rods superior to others on the
market. Available with both ARP 8740 and ARP 2000 bolts.

Pro Series I-Beam








The Manley Pro Series I-Beam rod has become the benchmark for fully
machined/billet style high end connecting rods in the performance industry.
Multiple weight designs targeting specific markets combined with our finely
tuned manufacturing process renders a truly outstanding product.

A WORD ABOUT HORSEPOWER RATINGS...
You will see that we list “horsepower ratings” for each different series/application of Manley connecting rods. However, it is very important to understand that these “ratings” are somewhat subjective. The critical factors that significantly influence the fatigue life of connecting rods (and the horsepower rating) are RPM, stroke, piston weight and power adders. In certain cases, our horsepower ratings may be conservative. Call our tech line if you are unsure based on your specific application.

“I have used Manley H-Beam rods for years
and they have proven to be a reliable choice.”
– David Reher






We’ve been so impressed with the strength
and durability that Manley rods provide we
made them standard in our “Pro Series” engine
lineup. I recommend Manley “M-Power” cranks
and rods to anyone looking for additional
strength at an exceptional value!!
- Scott Shafiroff
