Features:
If you’re serious about pushing your Cummins to its limits, the Carrillo CR_A59DC_0HS_7559B7H Connecting Rods are built to handle everything you can throw at them. These aren’t your average rods, they’re forged from Carrillo’s proprietary 4330M alloy, a material known for its incredible strength and fatigue resistance. Whether your truck is built for competition, high-horsepower street driving, or heavy towing, these rods deliver unmatched reliability under extreme cylinder pressures. Every set is fully machined to exacting tolerances, ensuring perfect balance and consistent performance across all cylinders. Carrillo’s attention to detail extends to the bolts as well, offering both H11 and MP35N options for high-RPM applications that demand extra clamping force. With superior thread design, these bolts distribute load evenly, improving both durability and fatigue life. When your build demands confidence and consistency at every RPM, these connecting rods give you the peace of mind to turn it up without hesitation.
The Carrillo CR_A59DC_0HS_7559B7H Connecting Rods are engineered for 1989 to 2018 Cummins 5.9L and 6.7L engines, offering professional-grade strength and precision for high-performance diesel builds. Each rod is machined from a proprietary 4330M alloy forging, chosen for its balance of strength, ductility, and fatigue resistance. Carrillo’s engineering team designed these rods to endure the extreme combustion forces common in high-boost, high-RPM diesel engines. The rods are available with two bolt configurations, the standard WMC-H7 H11 bolt rated at 220 ksi UTS, and the upgraded CARR-S7 MP35N bolt rated at 285 ksi UTS for extreme conditions. Both bolt options feature asymmetrical thread design, improving load distribution and increasing clamping efficiency during operation. Mahle steel bushings come standard, providing long-term durability and smooth pin operation under high load. For those running higher RPM or heavy fueling, optional cap relief is available to improve oil evacuation and bearing life, making these rods an ideal choice for both competition and extreme-duty applications.
