Skunk2 Alpha Series Honda D16/ZC 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 D16/ZC Connecting Rods are engineered for high-performance applications, crafted from high-quality 4340 chromoly steel. These rods feature an H-beam design that provides an optimal strength-to-weight ratio, ensuring durability under extreme conditions. Extensive material testing and close collaboration with the foundry guarantee each rod maintains superior quality, with comprehensive heat-treating, tempering, and shot-peening processes enhancing their strength and fatigue resistance.
Designed with precision, each rod is magna-fluxed to verify integrity and adherence to Skunk2's strict specifications. The two-piece forging process aligns the grain structure along the stress points, increasing overall strength and reliability. The straight H-beam configuration distributes stress evenly across the rod, reducing wear and supporting power outputs exceeding 900 horsepower. Dual oil passages at the pin ends facilitate superior lubrication and cooling, enhancing durability during high-performance engine cycles. The offset positioning of these passages ensures consistent lubrication around the wrist pin, contributing to longevity and smooth operation.
The set includes four rods with a length of 137.00mm and weighs approximately 509 grams each, designed to fit various Honda Civic and Civic del Sol models from 1992 to 1995. They are compatible with most pistons without requiring additional machining. Equipped with 3/8-inch ARP2000 bolts and bronze wrist pin bushings, these rods are balanced to within ±1 gram for smooth engine operation. Heat-treated and FEA analyzed, the Alpha Series rods are ideal for enthusiasts seeking reliable performance in turbocharged or naturally aspirated builds. Whether for street, track, or racing applications, these connecting rods deliver strength, precision, and consistency for demanding engines.
