Manley Performance
Steel Connecting Rods

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

Sportsmaster ® Series










The perfect rod for stock replacement, mild performance applications; particularly where class rules require a “stock appearing” rod. Aircraft quality 4340 alloy forgings, machined cap and outer beam and ARP cap screws make this Manley rod an ideal choice for many budget conscious racers. Lightweight and affordable.

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.
