CloseBearings
Clevite bearings, developed and proven over decades, set the industry standard for engineering quality.
In addition to Clevite® bearings being the choice bearings of NASCAR Performance, they succeed on
straight tracks as well. Every top NHRA nitro-fueled car from John Force in Funny Car to Larry Dixon in
Top Fuel puts their trust in Clevite. We have access to an extensive coverage for all domestic and import
light vehicle applications. -
CloseBushings
CP-Carrillo’s bushings are generally manufactured from Aluminum/ Silicon/ Bronze. As a custom connecting rod manufacturer we also offer a variety of other material such as Nickel/Tin/Copper and Beryllium Copper. In special and limited applications CP-Carrillo offers the option to run rods without bushings. This option requires the use of a special coated pin. Please consult our technical sales engineers for application information.

CloseFasteners
The fastener system of a high performance connecting rod is most likely the most critical unit of the assembly. As a result it is important that the fastener is installed per instructions and with recommended lube. CP-Carrillo has close to fifty years of experience of working with what have become the most recognized fasteners in the connecting rod industry. Much of this has come from experience which has been tested and validated repeatedly.
Each CP-Carrillo fastener design is based on a known yield load. During linear stretch of the bolt this load should never be reached. The recommended stretch value is 80% of yield load calculated in a tension – torque diagram.
Torque figures are the more commonly used method for tightening fasteners, however this is not CP-Carrillo’s preferred method and we will explain why. Torque is affected by numerous variables, all of which can alter the true preload figure you are trying to attain. Particularly, the lube utilized, the condition of the threads, the spot face, dimensional integrity, as well as other variables have an effect. Nearly all of these elements are alleviated if the assembler uses a “stretch” method. CP-Carrillo found that the consistency of high quality fasteners offers the least deviation when using the stretch method, with the result that the fastener will exhibit proper preload using designated stretch.
CP-Carrillo pays close attention to the above mentioned variables. Dimensional integrity is foremost -- the qualities of the fasteners have set the standard in the industry and we have continually looked at improved lubrication. The results of this continued effort is a new, improved lubrication for the fasteners. This is still molybdenum based lubrication grease, but with enhanced properties. This product offers an improved clamp load repeatability, greater resistance to high pressure and temperature (range -22F to 1200F), and no oil contamination. The coefficient of friction stays unchanged, even after several bolt re-tightening and loosening processes.
The implementation of this new lube is simply another example of CP-Carrillo’s efforts to continue to offer the finest connecting rod in the industry.
PRODUCT UPDATE – Pro Series 3/8 CARR FASTENERS (PN# BLT-CARR6-PS)
As load requirements have increased over the years, CP-Carrillo developed an improved 3/8 CARR fastener to meet the rigorous performance standards one expects from Carrillo connecting rods. This fastener, known as the 3/8 CARR Pro-Series, has been used in many forms of racing. This stronger, higher clamp load 3/8 PS CARR fastener is replacing our standard 3/8 CARR to provide the best performance fastener in every application. The 3/8 PS CARR bolt has a thicker shank and does requires more bolt stretch, to get the desired clamp load. Please follow the instructions closely.
The Standard 3/8 CARR fastener (PN# BLT-CARR6) has the head marking of S6-X-XXX
The Pro-Series 3/8 CARR fastener (PN# BLT-CARR6-PS) has the head marking S6-X-XXX-PS
Installation Instructions:
- Con rod supplied with 3/8 PS CARR fastener:
Use the listed stretch number of 0.0065-0.0075” to get the best performance of the PS Bolts.
- Replace existing 3/8 CARR fastener without resizing the big end:
Stretch the BLT-CARR6-PS bolts to 0.0060-0.0065”, it is safe to go slightly higher as much as 0.0070” but bore may change slightly. Values must not be lower than 0.0060”.
- Replacing 3/8 CARR fastener and resizing the big end:
Use the listed stretch number of 0.0065-0.0075” to get the best performance of the PS Bolts.
“Rather than simply offer instruction details we feel that if engine assemblers fully understand the dynamics of the fastener, successful implementation is achieved”.

Locks
CP-Carrillo offers different options for locks, depending on your preference and application.
Wire Locks are made from a High quality Carbon Spring Steel or Chrome Silicon based alloy. They are black Oxide coated, oil dripped and sealed to be non-corrosive.
Spiral Locks are made from high quality Carbon Steel and pre-tempered with uniform circular grain mirco structure. Blued, oil dipped and sealed to be non-corrosive.
SURE-Lox Non-Rotating Wire Locks CP-Carrillo has partnered exclusively with KRAMM-Lox to produce non-rotating wire locks for pistons. “SURE-Lox” are able to withstand very heavy loads and high RPMs. They are designed to directly replace standard wire locks with no additional machining to the piston and “SURE-Lox” will not rotate in the lock groove even under extreme conditions. They are available in most wrist pin sizes. Kramm Lox installation tools make assembling much easier without deforming locks. For more information, please contact our sales staff

ClosePins
A wrist pin, also known as a piston pin, is an important component in an internal combustion engine. It is the critical link between a piston and connecting rod, and is continually exposed to extremely high loads in alternating directions and it is also subjected to shearing and bending forces from the connecting rod.
Taking all these parameter in consideration, CP-Carrillo offers a wide variety of wrist pins to fit different applications and uses. Below is a selection of different materials and treatments available.

CloseRings
The principal function of the piston rings is to form a seal between the combustion chamber and the crankcase of the engine. The goal is to prevent combustion gases from passing into the crankcase and oil from passing into the combustion chamber. During the compression and power strokes, the compression ring seals the combustion gases and prevents blow-by. Although blow-by is not completely eliminated it is kept to an acceptable limit. During the compression and exhaust strokes the cylinder walls are lubricated with oil by throw off from the connecting rod bearings. Excess oil is wiped off by the piston rings. Not only does the oil ring have the responsibility of wiping the excess oil off the cylinder walls, but the job is also shared by all of the rings, leaving a fine layer of oil on the wall to provide lubrication for the following ring.
CP-Carrillo offers the latest materials and coatings available to keep pace with the growing trends in engine technology. We offer a variety of materials and coatings for piston rings ranging in diameter – from Automotive and Diesel, to Powersport and Marine.

PVD Rings
These rings are the next technology. Providing excellent wear, corrosion, and scuff resistance. The PDV coating adds hardness and toughness to the ring as well as helps reduce friction. This coating is better than traditional gas nitriding alone. For those pushing high HP levels and a lot of power these rings have a stronger top ring (1.2mm) that can withstand more cylinder pressure before the risk of fluttering and we recommend them for its friction/drag reduction against the cylinder. These rings are offered in a variety of bore sizes.
CPN Ring Sets
Small bore and Sport Compact engines with higher cylinder pressure require better sealing power than most other applications.
Our CPN ring sets are designed to meet those high demands.
Compatible with today's new cylinder materials, such as Nikasil, these high strength, low tension ring sets offer optimum sealing with minimum drag.
Each set consists of a gas nitrided steel 1.0mm top ring, a Taper hook groove (THG) Napier style 1.2mm second ring with a low tension 2.8mm flex vent oil ring. 2.0mm rings are available in the PDN2 ring sets.
- CPN is 1.0 1.2 2.8mm
- CPN2 is 1.0 1.2 2.0mm
- CPNG is 1.0 1.0 2.0mm
The bore size is incorporated in the part number: EXAMPLE: CPN-2874 = 2.874 bore
