Overview
The CP-Carrillo connecting rod with part number NI-TB48-1>-66437H is a high-performance component engineered specifically for the Nissan TB48 engine. It features a robust straight H-beam design, providing exceptional strength and rigidity under extreme load conditions. Forged from Carrilloy, a proprietary chrome-nickel-molybdenum-vanadium alloy steel, the rod offers superior fatigue resistance and durability. With a center-to-center length of 6.437 inches, it ensures precise fitment, while its 3/8-inch multiphase bolts deliver excellent clamping force for high-RPM stability. The rod includes a 2.3622-inch big-end bore, 1.290-inch big-end width, 23 mm pin bore, and a 1.020-inch pin-end width, offering compatibility with performance piston and crank configurations. Each rod is shot-peened, magnaflux-inspected, and Rockwell hardness tested to meet strict quality standards. Manufactured in the USA, it is ideal for turbocharged, nitrous, and high-output racing applications where reliability and strength are critical.
