Skunk2 Alpha Series Honda B16A Connecting Rods – Forged 4340 Chromoly Steel, Rated for Over 900 HP

Alpha Series Rods are forged from select 4340 chromoly steel and feature an H-beam design, resulting in the ultimate strength-to-weight ratio. 4340 chromoly is one of the strongest materials available, however, not all 4340 chromoly is the same. As such, Skunk2 relies on extensive material testing and works closely with its foundry to produce high-quality rods at an affordable price. Comprehensive heat-treating, tempering, and shot-peening processes together ensure that each Alpha Series Rod remains consistent and strong. Finally, each rod is magna-fluxed to ensure integrity and that each process has been completed thoroughly and according to Skunk2's rigid specifications. Skunk2's engineers spent nearly three years developing and testing its H-beam rod design. The results are one of the strongest beam configurations available, capable of handling more than 900 hp. Engineers made use of FEA (Finite Element Analysis) to determine high-stress points and implemented features to reduce wear and increase strength. Skunk2's straight design distributes stress across a larger area when compared to tapered rods, providing additional support where necessary. Alpha Series Rods are manufactured from two-piece forgings, resulting in optimal grain orientation along the rod cap for increased strength. By orienting the metal's grain in the direction of stress along the rod cap, perpendicular to the stress exerted along the beam, strength is significantly increased. Skunk2's two-piece forgings provide a precision-tight fit between the rod's cap and its beam without resorting to the brittle materials required by other processes. Alpha Series Rods also feature dual oil passages at their pin ends, providing additional lubrication and cooling, which leads to an even stronger, more durable rod. Unlike other designs, Skunk2's carefully positioned, offset oil passages help deliver lubrication around the entire wrist pin, during each phase of the engine cycle.

The Skunk2 Alpha Series Honda B16A Connecting Rods are engineered for high-performance applications, combining durability and precision to meet the demands of racing and enthusiast builds. Crafted from high-quality 4340 chromoly steel, these rods feature an H-beam design that provides an excellent strength-to-weight ratio, enabling them to handle over 900 horsepower reliably. Extensive material testing and close collaboration with the foundry ensure each rod maintains consistent quality through comprehensive heat-treating, tempering, and shot-peening processes. These procedures promote fatigue resistance and overall durability, making them suitable for extreme engine conditions. Each rod is magna-flux inspected to verify structural integrity, ensuring peace of mind during high-stress operation. The design incorporates dual oil passages at the pin ends, strategically positioned to enhance lubrication and cooling around the wrist pin during every engine cycle, which helps in reducing wear and extending the lifespan of the components. The two-piece forging construction aligns the grain flow along the stress direction, significantly increasing strength, while the straight H-beam shape distributes stress efficiently, preventing premature failure. The rods are compatible with most pistons without additional machining, and feature bronze wrist pin bushings for smooth operation. Weighing approximately 19 ounces each and measuring 5.3 inches in length, these rods are balanced to within one gram for optimal engine performance. With a proven design validated through Finite Element Analysis (FEA), Skunk2's Alpha Series rods are a reliable choice for Honda B16A engines seeking maximum power and durability in street or race conditions.
