Why Do We Recommend Carrillo Rods?


It all comes down to time-tested & trusted quality and function wrapped together for a great price.


Carrillo goes above & beyond by having their rods heat validated, by the supplier and by an independent metallurgist who confirms the desired physical and chemical properties of steel. Each lot of bolts are sample tested destructively for both ultimate tensile strength as well as levels of fatigue.

When it comes to rods, Carrillo uses proprietary chrome, moly, nickel, and vanadium alloy (meets all VAR, vacuum arc re-melt ASTM standards).

All heat treat processes are done by a mar-aged operation, resulting in UTS of 195,000 with a yield of 182,000 – this maintains the critical elements of low notch-sensitivity and ductility.

All Carrillo billet connecting rods are manufactured from an oversized forging which results in a proper grainflow – this process removes any potential inclusions or surface conversions generated by the forging process. Carrillo’s CNC machines validate dimensional integrity by probing. At least twice during the production process each part is magnafluxed. Each piece is also Rockwell tested to validate the heat treat procedure. Finally, to complete the part, a final shotpeen operation is done.

Carrillo has been in the custom rod business since 1963 and has provided custom & prototype rods to every major automotive & motorcycle venue. So, they know their stuff.

AirDog II-4G Is Now Available!

The new patented AirDog II-4G ® is the next big thing in the fuel delivery system resulting in a smaller, longer lasting, more efficient, and quieter lift pump.

The new motor design produces 3 benefits for the AirDog II-4G ® fuel system.

  1. This new system utilizes an intermediate pump shaft that moves the electric motor away from the fuel — this helps to prevent “wet motors”.
  2. The motor’s self-aligning capability requires less maintenance and increases the system’s endurance & tolerance — resulting in a longer pump life.
  3. The quieter, low amperage motor provides longer drivability and contributes to a significant reduction in noise.

AirDog® is proud to announce that the AirDog II-4G® is the quietest fuel system in the diesel market!

The AirDog II-4G® is available for modified Dodge, Chevy, and Ford applications.

The new fuel system will support between 500 and 800 horsepower with a flow rate of 165 gph. It is best suited for light to moderate modifications. Applications available for the fuel delivery system are Dodge, Chevy, and 6.4L and 6.7L Ford diesel trucks. Ford applications are currently only available in these models.

So, what can the AirDog II-4G® do for you?

The benefits of the system are immediately apparent. The removal of contaminants in diesel fuel, such as air, water vapor, and debris provide increases in power and performance.

This is reflected by:

  • Smoother acceleration and idle
  • Throttle response is improved
  • The elimination of hard starts

As the amount of air and water in the fuel decreases, fuel economy improves which leads to increased savings for you. Removing contaminants, such as air/water/debris, allows for pure diesel fuel to enter the combustion chamber through the injectors, safeguarding the engine and providing a full burn which means you no longer have to worry about wasting fuel.
