Part Description |
Manufactured from USA made oversized proprietary steel forgings to enable proper grain flow and guarantee removal of any surface inclusions, CP-Carrillo ensures strength and durability of each Carrillo rod. Consistent and reliable from the first point of precision manufacturing all the way to extreme uses in racing world, exclusive Carrillo H beam and Pro (S)A designs offer the highest strength-to-weight ratio; 100 traceability; multi-step final inspection; |
Fatigue and over-revving are the two major causes of connecting rod failure. CP Carrillo rods are not only stronger than OEM rods, but they are lighter weight, which means less weight for the engine to throw around at high RPM, and more horsepower output.

What bolts do these conrods use and how should I tighten them?
These rods use ARP conrod bolts, usually ARP2000 as standard with L19 or CA625+ available on some models. ARP2000 bolts are generally torqued to around 55 ft-lb for 3/8 inch and around 75 ft-lb for 7/16 inch when using ARP Ultra-Torque lube. L19 bolts must be tightened by stretch, not torque. Always refer to the latest ARP instructions for exact specifications.
Do these conrods have a horsepower rating or warranty?
No. Like other performance rods, they do not carry a horsepower or performance warranty. Spool warrants workmanship before installation, but once fitted, power handling depends entirely on machining, clearances, tuning, fuel, boost level and rpm.
Do the big end and small end need machining?
They often do. Crank journals and pin bores vary between engines, so your builder should measure the big end oil clearance and small end pin clearance and hone as required before assembly.
What are the key features of the Carrillo PRO-A Conrod for the Honda CRF450R '02-'08?
The Carrillo PRO-A Conrod is manufactured from USA-made oversized proprietary steel forgings, ensuring optimal grain flow and the removal of surface inclusions. It features a high strength-to-weight ratio, making it suitable for extreme racing applications. The conrod is designed with precision manufacturing and undergoes multi-step final inspection for consistent reliability.
What machining considerations should I keep in mind when installing the Carrillo PRO-A Conrod?
When installing the Carrillo PRO-A Conrod, it's essential to check the big-end and small-end for proper fitment. Due to manufacturing tolerances, honing may be required to achieve the correct clearances for the crankshaft and piston pin. Always consult with your engine builder for specific machining requirements.
What is the weight of the Carrillo PRO-A Conrod, and how does it affect performance?
The Carrillo PRO-A Conrod weighs 246 grams. A lighter conrod reduces the overall rotating mass, allowing for quicker revs and improved throttle response. This can contribute to better performance, particularly in high RPM applications, but ensure that the rest of the engine components are compatible with the weight reduction.
How does the design of the Carrillo PRO-A Conrod enhance its durability?
The Carrillo PRO-A Conrod features an H-beam design that provides superior strength and rigidity compared to traditional conrod shapes. This design, combined with the high-quality steel material, helps to withstand the stresses of high RPM and extreme loads, reducing the risk of fatigue and failure.
What are the recommended applications for the Carrillo PRO-A Conrod?
The Carrillo PRO-A Conrod is specifically designed for the Honda CRF450R models from 2002 to 2008. It is ideal for off-road and dirt bike racing applications where high performance and reliability are critical. Ensure that your engine setup is tuned for optimal performance to fully utilise the benefits of this conrod.
