Alpha Rods are forged from select 4340 chromoly steel and feature a straight H-beam design, resulting in the ultimate strength-to-weight ratio. The F22C Rods were designed for both Naturally Aspirated and Forced Induction use and are rated to withstand up to 900 hp.
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. 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. 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. Connecting rod bolts endure more stress than any other engine fastener, therefor each Alpha Series Rod features high-quality, Skunk2-branded, 3/8-inch ARP2000 bolts. ARP2000 rod bolts are forged, heat-treated, precision-machined, and capable of clamping loads as high as 220,000 psi.
Precision-machined, bronze wrist pin bushings are also fitted to each Alpha Series Rod for increased wear resistance and are compatible with most aftermarket pistons without additional machining.
