Eagle offers balancing of the entire rotating assembly on their Hines equipment. This saved us the hassle of having it done locally, and it let us get to the assembly stage that much faster. Eagle is known for their high-quality connecting rods, and these forged 6.000-inch 5140 SIR I-beam units are no exception. They’re bushed to work with full floating piston pins. The rods also utilize ARP wave-lock fasteners and have alignment sleeves for easier assembly. The forged pistons are Mahle slugs that came coated right out of the box. The choice to run forged pistons means we’re good to go if we want to toss on a 125 shot of nitrous.
