Carrillo SCR4849-6 Pro-H Straight H-Beam Connecting Rods Nissan VQ35 5.676in 3/8 CARR Bolt

Designed for high-performance and racing applications, these rods are built to withstand extreme cylinder pressures and high-RPM abuse that would destroy lesser components.

Key Features:

• Pro-H Straight H-Beam Design — The stoutest beam configuration available from Carrillo, optimized for maximum strength under the most demanding race conditions
• 5.676 in. Center-to-Center Length — Matches OEM stroke geometry for direct-replacement performance upgrades
• 22mm Wrist Pin Bore — Bushed, full-floating pin design for superior load distribution and reduced wrist pin wear
• 3/8 in. CARR Bolt Fasteners — Carrillo's own high-strength proprietary rod bolts, engineered to exact yield specifications for reliable high-RPM clamping force
• 2.1654 in. Big End Bore — Precision-machined to OEM journal dimensions (55.000mm)
• 0.818 in. Big End & Pin End Width — Matched widths on both ends for proper bearing and wrist pin alignment
• 544g Advertised Weight (per rod) — Produced in matched sets for consistent rotating assembly balance
• Proprietary Carrilloy Steel — A chrome, nickel, moly, vanadium alloy meeting all VAR (vacuum arc re-melt) ASTM standards for exceptional tensile strength and fatigue resistance
• Shot-Peened Finish — Cold-working surface treatment that relieves tensile stress and dramatically improves fatigue life
• Magnaflux Inspected — Each rod is magnaflux tested twice during production to identify any surface flaws before leaving the factory
• Rockwell Hardness Tested — Every rod is tested to validate the heat treat procedure for consistent hardness across the set
• Laser-Etched Job Number — Full traceability from raw material to finished product
• Made in the USA — Manufactured at CP-Carrillo's facility in Irvine, California

CP-Carrillo connecting rods are manufactured from oversized proprietary steel forgings, ensuring proper grain flow and eliminating surface inclusions generated during the forging process. All critical CNC machines are equipped with probing to validate dimensional integrity at every stage of production. The SCR4849-6 is the ideal foundation for a high-output VQ35 build, from forced-induction street performance to all-out competition engines.
