The Geometry of Speed

When you are building a dedicated high-RPM race engine, the standard Barra geometry becomes a limitation. The Atomic "Destroker" FatRod is designed specifically for our 86mm Stroke (3.5L) Crankshaft. At 161.29mm (6.350") long, this rod significantly improves the rod-to-stroke ratio compared to the factory setup.

The Atomic Solution

Built on our legendary "FatRod" architecture, these rods feature the same 13% wider H-beam profile and aerospace billet steel construction that has resulted in zero failures since 2004. They come standard with CA625 High-Tensile Bolts for ultimate clamping force and feature our signature pressure-fed pin oiling to keep wrist pins alive at 9000+ RPM.

Engineered for 9000+ RPM

High RPM kills wrist pins. We engineered specific oil pathways to keep your rotating assembly alive where others fail.

• Pressure-Fed Pin Oiling: A dedicated channel forces pressurized oil directly into the wrist pin bushing, critical for the high inertial loads of a de-stroked engine.
• Piston Crown Cooling: Built-in oil squirters spray the underside of the piston crown, pulling heat out of the combustion chamber to resist detonation.
• CA625 Fasteners: Every set comes pre-fitted with CA625 bolts, offering superior clamping force for extreme RPM stability.
