Why A2Speed Uses CP-Carrillo Pistons

You’ve undoubtable heard the name CP-Carrillo before. They make some of the best pistons on the market today! CP-Carrillo excels in making pistons for hardcore racing engines. We decided it was time to bring their innovative, high performance pistons to the HEMI market in our A2Speed / Ray Barton stroker engines. Specifically, we are using CP-Carrillo’s bullet series as the flagship of our high performance rotating assembly.

Why CP-Carrillo Bullet Series

2618 Aluminum Alloy


CP-Carrillo utilizes a 2618 aluminum alloy allowing for maximum strength and resistance to large shock loads such as detonation. 2618 is more flexible than 4032 pistons thus can handle extreme loads better, and can move more before reaching their fracture point.

CP-Carrillo Bullet Pistons

Duel Forced Pin Oilers


This feature doubles the amount of oil, over a single pin configuration, that reaches the cylinder wall / wrist pin bore. This helps increase the durability of your high performance HEMI engine.

CP-Carrillo Bullet Pistons

Anti-Detonation Grooves (Contact Reduction Grooves)


These groves are intended to prevent contact between the piston and cylinder in high RPM / High Heat situations. An added feature of these grooves is that it protects / disrupts detonation impacts from damaging the top ring.

CP-Carrillo Accumulator Groove

Accumulator Groove


These grooves in the second ring land accumulate left over gasses from the combustion chamber alleviating ring flutter in the top ring and early second ring wear. Overall this improves your ring seal and durability.

CP-Carrillo Accumulator Groove

Chromoly Wrist Pins with Wire Locks


CP-Carrillo utilizes case hardened wrist pins made using a computerized gas process. These wrist pins are put through a subzero heat-treating process to improve material strength and grain structure.

CP-Carrillo Accumulator Groove

Valve Reliefs


Valve reliefs are put into the piston to improve flame travel and cross flow in the chamber during the overlap stroke.

CP-Carrillo Accumulator Groove

ISO 9000 Certified


CP-Carrillo bullet pistons are ISO certified, meaning they meet the strictest requirements and have been tested to ensure that you have an extremely durable high performance product.

  • Our Quality
A2Speed is an employee owned automotive performance parts company, specializing in the Gen III HEMI engine and the cars & trucks it powers. Just like you we are Hemi enthusiasts, and like you we are only interested in proven performance solutions. Good enough isn’t. People who invest in performance modifications want parts that last decades, not years. The effort is only valuable if the result is better than good enough, and frankly these days that’s hard to do.

A2Speed’s GEN III HEMI Background

Many of us at A2Speed have been working on the Gen III since its inception. As a team we are immersed in the Hemi world. We own, drive, modify, race and occasionally…break them. We use this experience to create SOLUTIONS, not just parts. Automotive engineering has advanced such that it is often difficult to improve on the work done by the OEMs. Difficult, not impossible. Utilizing advanced 3D modeling, CFD and stress simulations coupled with rapid prototyping, allow for the development of specialized parts that would be impractical at OEM volumes. Solutions validated with real world testing. Craftsmen level quality; and because we don’t have the layered overhead, our prices are often at or below the OEM price.

Advanced Aerospace Grade Machining

Production manufacturing is performed by partner companies that have proven track records for quality and timely deliveries. We look for certifications such as ISO-9001 and AS-9100 along with ITAR and GIDEP registrations. Several of the companies we work with regularly supply major aerospace firms and the DOD. Why use outside machining services? So that you get a better part at a better price. By utilizing only the machine cycles we need, and leveraging the superior skills and years of experience, A2Speed can give you exceptional quality at truly affordable prices.
