Carrillo Connecting Rods are manufactured from a proprietary steel, manufactured and forged to custom specifications.

After experimenting with virtually every other reasonable material, Carrillo found a chromium/nickel/vanadium/molybdenum-forged alloy to be the best product to meet the stringent requirements of performance motors.

Through out the manufacturing process Carrillo rods are inspected and measured to uphold high quality standards.

When you go with Carrillo – you go with quality.

Throughout the manufacturing process and before leaving Carrillo's facility, their rods are under the control of a rigorous Quality Assurance system. Each rod is subjected to a variety of quality checks, to ensure dimensions meet our stringent tolerance requirements. Carrillo employs a variety of testing equipment to accurately assess these tolerances, including a CMM, Air and Height-Gauges, a 2D measuring system to name just a few.

The initial quality assurance starts with their selection of steel, followed by a strict forging and heat treating process. As a rod moves through the manufacturing process, quality assurance follows every step of the process; testing dimensional integrity and quality, providing a paper trail of certification through out the entire manufacturing and shipping process.

Every rod leaves Carrillo's facility with a specification card. This spec card displays a part number, critical dimensions, weights and job number, all for ease of identification and tracking.

The Carrillo Pro-Super-A (SA) bridges the gap between the Pro-H and Pro-A applications. With an increased beam thickness, the Super A-Beam design has a higher load capacity than the regular A-beam design.

Rods sold as a COMPLETE Matched Set.
