Weight is the enemy of RPM. Standard H-beam rods are strong, but often heavy. Superleggera (Italian for "Super Light") rods are engineered to solve this by shaving critical reciprocating mass without sacrificing the strength needed for 1000hp.
💡 DID YOU KNOW?
Zero Failures Since 2004. That's right. In over two decades of production, we have never recorded a single structural failure of an Atomic H-Beam conrod. We built the Superleggera to continue that legacy while weighing in at just 722g per rod.
The Atomic Solution
We combined aerospace-grade billet steel with advanced FEA (Finite Element Analysis) to create a rod that balances elite performance with everyday reliability. Featuring our signature H-beam design and CA625 bolts (stronger than ARP2000), these rods are capable of 8500+ RPM and 1000hp+ with total confidence.
The 722g Lightweight Powerhouse.
Detail: Crown Cooling and Pressure-Fed Pin Oiling.
2. Advanced Oil Management
High RPM kills wrist pins. We engineered specific oil pathways to keep your rotating assembly alive.
Pressure-Fed Pin Oiling: A dedicated channel forces pressurized oil directly into the wrist pin bushing, significantly extending pin life under high load.
Crown Cooling: Built-in oil squirters spray the underside of the piston crown, pulling heat out of the combustion chamber and reducing the risk of detonation.
CA625 Fasteners: We don't skip on bolts. Every set comes pre-fitted with CA625 bolts, offering superior clamping force for high-RPM stability.
Final Sizing Required: The small end bushings are supplied unfinished at .866". This allows your engine builder to hone them to the perfect clearance for your specific gudgeon pin (Metric 22mm vs Imperial .866").
Big End Bore: Finished to 2.2394".
Pin Compatibility: Compatible with all major piston brands including Cosworth, Mahle, and JE.
