#1.Demotor I-Beam Connecting Rods

When it comes to the best connecting rods, we think that the Demotor I-Beam Connecting Rods really offer the best value in terms of performance and quality to price. As the name implies, these are I-beam connecting rods that are manufactured from high quality 5140 chromoly steel. They are also are x-rayed and ultrasonically tested with all surfaces.

Additionally, they have a floating wrist pin style with a 12 point bolt head style. They are also precision machined, honed journal, and pin ends. The fastener yield strength is 200,000 PSI. This is sold as a set of 8 and we can say for sure that for the price, you won’t be able to find another set with the same quality and durability as these.

#2.Eagle Specialty Products Connecting Rods

Next, we have the Eagle Specialty Products Connecting Rods, which are the best connecting rods for those who want outstanding strength and reliability. They’re forged from 5140 steel. Also, these connecting rods come in both press-fit and bushed pin models. We like how its lightweight design places less stress than its competition on the rest of your rotating assembly.

This in turns helps increases engine life as well as being better at handling high-rpm use. Also, as a safe measure and stress relief, the rods are sonic-tested, x-rayed, magnafluxed, and shot-peened. Finally, we really like the fact that the rods come with 12-point ARP Wave-Lok rod bolts. They are also weight-matched to within 2 grams.

#3.Speedway Motors Small H-Beam Connecting Rods

Another good option for the best connecting rods is the Speedway Motors Small H-Beam Connecting Rods. This is a weight matched set of 8 heavy duty H-beam rods in 5.7 inch lengths. You can also get the same set with a 6 inch length also sold by Speedway Motors. This particular rod features a full floating wrist pin in silicon bronze bushing.

There is also a precision bolt bushing to positively locate the cap and it features 8640 PCE 7/16″ cap screws. Also, one thing to check to make sure is if it is legal with your state. All in all, in our honest opinion, we think these connecting rods are pretty good quality. Sure there are more expensive ones out there but you just don’t get a crazy performance boost by paying more money.

#4.Scat Crankshafts I-Beam Connecting Rods

The Scat Crankshafts I-Beam is a pretty good option if you are in the need of solid connecting rods. It has a very lightweight which keeps rotating mass low for quick rpm. If you run the numbers, these rods are a very good bargain and a much better alternative to having your old rods rebuilt. Overall, this set of 8 met all of our expectations and more.

The one thing we wish Scat had told us about is just providing a bit more information. For example, in order to get the right torque specification, you’ll have to figure out the name of your rod bolts. But overall, this is a solid set of connecting rods with excellent durability. And we give their customer service two thumbs up as they are very responsive and have a lot of patience.

You probably won’t get a wild boost in performance for paying the premium, but if you’ve got money to spend and want the best quality, this is it.
