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 specific applications for the Carrillo PRO-H Conrod PSR5417?
The Carrillo PRO-H Conrod PSR5417 is designed for various KTM models including the 94-06 620 LC4, '94-97 DUKE, '98-01 620 SC, '02-06 625 SX & SM, and '98-06 640 LC4 & DUKE II. Ensure compatibility with your specific engine variant before installation.
What material is the Carrillo PRO-H Conrod made from?
The Carrillo PRO-H Conrod PSR5417 is manufactured from 4330M steel, which provides a high strength-to-weight ratio, making it suitable for both performance and durability in demanding applications.
What machining considerations should I keep in mind when installing this conrod?
When installing the Carrillo PRO-H Conrod PSR5417, be aware that the big end may require honing to ensure proper fitment due to potential factory journal size variations. Always check clearances and tolerances as per your engine specifications.
How does the weight of the Carrillo PRO-H Conrod affect engine performance?
The Carrillo PRO-H Conrod PSR5417 weighs approximately 497 grams. Its lighter weight compared to OEM rods reduces rotational mass, which can lead to improved throttle response and higher RPM capabilities, ultimately contributing to better overall engine performance.
What is the pin diameter for the Carrillo PRO-H Conrod PSR5417?
The pin diameter for the Carrillo PRO-H Conrod PSR5417 is 22 mm. Ensure that your piston pin matches this specification for proper fitment and function.
