If you're diving into serious performance upgrades for your Chevy small block, these Forged 4340 Steel H-Beam Connecting Rods are definitely worth a look. Crafted from high-quality 4340 steel, these rods are built to take a beating—perfect for those who push their engines to the limit. The two-piece forging process gives them a solid foundation, and the fully machined and shot-peened surface not only looks good but enhances durability too.
Measuring in at a precise 6.200 inches center-to-center, these rods are sold as a weight-matched set, which is crucial for maintaining balance in high-performance applications. You want every bit of power to translate smoothly, right? With a big end width of 0.94 inches and a pin end width of 1.06 inches, these rods are designed to fit snugly and securely. Plus, they’re bush for full-floating piston pins, which means less friction and more efficiency when you’re revving high.
Now, let's talk bolts. These rods come with 7/16" ARP 8740 bolts that are known for their strength and reliability. You’ll want to torque them to 63 ft-lbs using ARP moly lube, ensuring everything stays tight under pressure. The housing bore is 2.225 inches, and the rod journal measures 2.1 inches. It’s all about those little details that add up to big performance gains.
One thing to keep in mind is that while these rods are designed with a universal fitment in mind, it’s always a good idea to do your homework to make sure they’ll work with your specific setup. And just a heads up, this product contains nickel, which is known to the State of California to cause cancer, so be sure to check out the Prop 65 warnings if that’s a concern for you.
In short, if you're serious about competition and want to push your engine to the next level, these ESP 4340 Rods might just be what you need to get there. They’re tough, reliable, and ready to help you unleash some serious horsepower.
