Carrillo BF6152-STD Bullet Series Pro-H Connecting Rod Standard Bore

The Carrillo BF6152-STD is a Bullet Series connecting rod engineered for high-performance Ford applications. Featuring a 6.152" rod length at standard bore sizing, this rod delivers the proven strength and precision that CP-Carrillo is known for worldwide, at an accessible price point for serious performance builders.

CP-Carrillo's Bullet Series was developed to bring race-proven connecting rod technology to a broader range of performance builds. Manufactured in the USA from CP-Carrillo's proprietary Carrilloy steel — a chrome, nickel, moly, vanadium alloy meeting all VAR (vacuum arc re-melt) ASTM standards — each rod is forged from an oversized blank to ensure proper grain flow and removal of any surface inclusions.

Key Features:

• Bullet Series Pro-H beam design for high-strength, high-horsepower applications
• Proprietary Carrilloy steel: chrome, nickel, moly, vanadium alloy with VAR ASTM certification
• 6.152" rod length, standard (STD) bore sizing
• Manufactured in the USA from oversized forgings for proper grain flow
• Magnaflux inspected at least twice during production for structural integrity
• Rockwell tested to validate heat treat procedure
• Shot-peened surface finish to relieve tensile stress and increase fatigue life
• Laser-etched job number for full traceability
• Compatible with Carrillo WMC (H11 tool steel, 220,000 UTS) or CARR (Multiphase, 285,000 UTS) rod bolt options

Every CP-Carrillo rod undergoes a rigorous multi-step quality control process including CNC machining with dimensional probing, double magnaflux inspection, Rockwell hardness testing, and a final shot-peen operation. The result is a connecting rod that delivers consistent, reliable performance from street builds to demanding race environments.
