Skunk2 Honda and Acura K24A/Z Ultra Rods

Skunk2 Racing Ultra rods are manufactured from forged 4340 Chromoly steel then heat treated for ultimate strength. Skunk2 Racing Ultra rods are an x-beam style which greatly reduces weight while maintaining strength by removing material and strategically shaping the beam. This results in a very high strength to weight ratio and is great for circuit and drag racing. The ribs / straps on the pin end increase strength and stiffness under high loads and engine speeds. The step on the big end (crank journal side) is for strength and rigidity to maintain roundness.

Connecting Rods, Ultra Series X-Beam Forged 4340 Chromoly Steel Connecting Rods 2012 Honda Civic Si K24

Skunk2 Racing Ultra Series connecting rods are manufactured from forged 4340 chromoly steel. All forgings are then fully machined and subjected to a battery of processes that include heat treating, shot peening, and magnafluxing to insure the ultimate in strength, and each set is balanced to within +/- 1.5 grams. The connecting rods design greatly reduces weight, while maintaining strength by removing material and strategically shaping the beam; resulting in a very high strength to weight ratio, making them great for circuit and drag racing. The ribs and straps on the pin end increase strength and stiffness under high engine loads and engine speeds. The step on the big-end—on the crank journal side—is designed for strength, rigidity, and to maintain roundness. These features, along with ARP hardware, provides you with top-of-the-line connecting rods that can handle most anything you can throw at them.
