CP-Carrillo Connecting Rods
CP-Carrillo was founded in 1963 with one goal in mind: providing performance enthusiasts with the best possible internal engine components for their high-horsepower applications. Pistons and connecting rods are crucial components in high-horsepower engines and CP-Carrillo strives to deliver durable upgrades for all types of performance applications. CP-Carrillo designs and constructs their products in a state-of-the-art manufacturing plant in Irvine, California. Along with decades of automotive experience, CP-Carrillo utilizes cutting-edge technology to enhance their product lineup to ensure they deliver a long service life.
Through in-depth research, data analyzing, and precise CNC-machining, you can be sure the pistons and connecting rods from CP-Carrillo will provide accurate fitment, form, and function. All CP-Carrillo engine components go through multi-step inspections to ensure quality and durability. CP-Carrillo components are constructed from heavy-duty materials like billet aluminum and forged steel to withstand the harshest conditions. With products like the Hybrid Piston & Rod Kits, Pro-H Connecting Rods with H11 or CARR Bolts, and High-Performance Pistons, CP-Carrillo has the durable engine parts your truck needs. Whether you’re rebuilding the engine in your heavy-duty tow rig or getting your truck ready for the track, XDP has you covered with CP-Carrillo pistons and connecting rods. XDP carries a wide inventory of high-quality pistons and connecting rods for your Ford, GM, or Dodge Ram diesel engine.
Frequently Asked Questions
What is Carrilloy?
CP-Carrillo uses a proprietary 4330m alloy steel to manufacture its connecting rods, named Carrilloy. It is a chrome, nickel, moly, vanadium alloy which meets all VAR (vacuum arc re-melt ASTM standards). Carrilloy is simply a modification of an existing SAE specification. CP-Carillo tightens up the acceptable attributes of the heat as it is manufactured. The heat is validated, both by the supplier and an independent metallurgist whom confirm the desired physical and chemical properties of steel.
What is the difference between H11 and CARR Fasteners?
CP-Carrillo offers two types of fasteners: H11 tools steel (WMC) and a Multiphase (CARR) Fastener. The difference is in the material and the longevity. The H11 tool steel bolts feature a UTS of 220 KSI and are good for about 15-18 torque cycles. The CARR Multiphase fasteners feature a UTS of 285 KSI and are good for indefinite torquing's when stretch method is followed for installation.
What makes CP-Carrillo different from mainstream parts?
All critical CNC machines at CP-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 controlled and validated shot peen operation completes the part. Once manufacture is completed, the rod a job number is lasered for traceability.
Does CP-Carillo Rockwell test each connecting rod?
Yes, each connecting rod is Rockwell tested to validate the heat treat procedure. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload.
Does CP-Carillo Magnaflux their connecting rods?
Yes, actually twice. Magnetic Particle Testing, also referred to as MPI Testing and Magnaflux Testing, helps identify surface flaws in metal products that can be magnetized. MPI testing is performed to help identify cracks, laps, and seams in the forgings during and after production.
What's special about CP-Carillo Rod Forgings?
All CP-Carrillo Steel 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. By insuring proper grain flow with their proprietary material, the strength and durability of each rod becomes more consistent and reliable from the first point of manufacturing all the way to the extreme uses in the racing world.
Why are CP-Carrillo connecting rods Shotpeened?
Shot peening relieves tensile stresses built up in the grinding process and replaces them with beneficial compressive stresses and increase fatigue life. Shot peening is a cold working process in which the surface of a part is bombarded with small spherical media called shot. Each piece of shot striking the material, acts as a tiny peening hammer, imparting to the surface a small indentation or dimple. Since nearly all fatigue and stress corrosion failures originate at the surface of a part, compressive stresses induced by shot peening provide considerable increases in part life.
