Overview
The CP-Carrillo NI-VR38>66496S Pro-H connecting rod is a premium forged component designed for the Nissan VR38DETT engine found in the R35 GT-R. It features a straight H-beam design, delivering exceptional strength and rigidity ideal for high-performance and high-RPM environments. The rod is forged from Carrilloy, a proprietary chrome-nickel-molybdenum-vanadium alloy steel known for its outstanding fatigue resistance and durability. With a center-to-center length of 6.496 inches, it ensures precise fitment and performance. Equipped with 3/8-inch multiphase bolts, the rod offers superior clamping force and reliability under extreme loads. The big-end bore measures 2.3229 inches, with a big-end and pin-end width of 0.896 inches, and a pin bore of 23 mm—dimensions that accommodate the demanding tolerances of racing and high-output builds. Each rod is shot-peened, magnaflux-inspected, Rockwell hardness tested, and individually balanced to ensure consistent quality and traceability. Manufactured in the USA, it is ideally suited for turbocharged, nitrous, or track-focused GT-R applications where strength, precision, and reliability are critical.
