Skunk2 Alpha Series Honda B18C Connecting Rods

When you're rebuilding the heart of your 1994-2001 Acura Integra, especially for a performance build, you need connecting rods that can handle the stress. This set of Skunk2 Alpha Series connecting rods is forged from 4340 chromoly steel, a material known for its strength, and features an H-beam design. Skunk2 spent years developing this H-beam configuration, which is capable of supporting over 900 horsepower, making it a solid choice for high-output B18C engines.

Skunk2 goes the extra mile with their material sourcing and testing, working closely with their foundry to ensure consistency and strength in every rod. These rods undergo comprehensive heat-treating, tempering, and shot-peening processes to reduce fatigue and ensure they remain strong under load. Each rod is also magna-fluxed to verify its integrity. The H-beam design, analyzed using FEA, distributes stress effectively, and the straight design offers more support than tapered rods. They are manufactured from two-piece forgings, which allows for optimal grain orientation along the rod cap for increased strength where it's needed most. You'll also find dual oil passages at the pin ends, designed to deliver extra lubrication and cooling to the wrist pin area throughout the engine cycle, contributing to a more durable rod.

This set includes four connecting rods, each measuring 138.00mm in length and weighing approximately 489 grams. They come equipped with 3/8-inch ARP2000 bolts and bronze wrist pin bushings, and are balanced to within 1 gram. Skunk2 also includes a specialized lubricant for the bolts. These rods are designed to work with most pistons without requiring additional machining at the pin end.
