Description

The Carrillo A-Beam Rod is a lightweight, aerodynamic rod that will get the job done while reducing rotating mass, and improving crankcase widage characteristics. Reducing the mass of the rotating assembly allows the engine to spin more freely with less drag. This lets the engine work more on propelling you faster, and less on turning its clunky components. Carrillo is known for being the best of the best in the connecting rod world. Carrillo is synonymous with "unbreakable". The A-Beam is not their unbreakable rod, however it IS their LIGHTEST and LEAST EXPENSIVE rod for this application. 

We carry the entire Carrillo lineup so if you are looking to make more power than this smartly designed A-Beam can handle, please contact us first so we can help you determine the best setup for your build.
Carrillo uses proprietary chrome, nickel, moly, vanadium alloy which meets all VAR (vacuum arc re-melt ASTM standards). The heat is validated, both by the supplier and an independent metallurgist whom confirm the desired physical and chemical properties of steel.

All heat treat processes are via a mar-aged operation, resulting in UTS of 195,000 with a yield of 182,000 while maintaining the critical elements of low notch-sensitivity and ductility.

All Carrillo connecting rods are manufactured from an oversized forging resulting in the proper grainflow as well as the surface removal of any potential inclusions or surface conversions generated by the forging process. All critical CNC machines at Carrillo are equipped with probing to accurately validate dimensional integrity. In the production process each part is magnafluxed at least twice, further each piece is Rockwell tested to validate the heat treat procedure. A final shotpeen operation completes the part.

In addition to our well known H beam connecting rod, we offer an A beam configuration as well. The A beam configuration is available in a Pro-A, Pro-A-Ltd and Pro-Super A (SA) and Heavy Duty configurations.

Typically, the Pro-A beam configuration is well suited for less demanding, more economical, high-performance, aftermarket applications. Pro-A-Ltd connecting rods are designed for limited and restricted motor applications. And the Carrillo Pro-Super-A (SA) bridges the gap between the Pro-H and Pro-A applications.
