Skunk2 Alpha Series Honda K24A/Z Connecting Rods

Forged from 4340 chromoly steel, these Skunk2 Alpha Series connecting rods are built for serious engine work, especially in your 2004-2008 Acura TSX. The straight H-beam design is chosen for its excellent strength-to-weight ratio, meaning you get robust performance without adding unnecessary mass to your rotating assembly. Skunk2 carefully sources their 4340 chromoly, ensuring consistency and strength through extensive testing and working closely with their foundry. This attention to material quality is crucial for components that handle the intense forces inside a high-performance engine.

Beyond the base material, these rods undergo comprehensive heat-treating, tempering, and shot-peening processes. Shot-peening, in particular, helps reduce fatigue and increase the rod's lifespan by creating a more resilient surface. Each rod is also magna-fluxed to verify its structural integrity and confirm that all manufacturing steps meet Skunk2's strict specifications. You'll also find dual-pin oil passages designed to improve lubrication and further enhance strength, along with bronze wrist pin bushings that are compatible with most pistons without needing extra machining. They come balanced to within 1 gram and include 3/8-inch ARP2000 bolts, ready for installation in your K24A or K24Z engine.

This set includes four connecting rods, each measuring 152.00mm in length and weighing approximately 491 grams. They are engineered to handle over 900 horsepower, making them a solid choice for builds aiming for significant power gains. Remember to consult your engine builder or service manual for specific installation procedures and torque specifications.
