Carrillo SCR5464-6 Porsche 3.2/3.3 Pro-H 5.000in. Connecting Rods

Designed for high-performance street, track, and racing applications, these rods are a direct upgrade over the factory Porsche connecting rods, delivering far superior strength and durability.

Key Features:

• Pro-H Straight H-Beam Design: The stoutest H-beam configuration available from Carrillo, engineered to handle the most extreme cylinder pressures and engine speeds
• 5.000 in. Center-to-Center Length — precisely matched for Porsche 3.2/3.3L engine architecture
• 23mm Wrist Pin Bore with bushed, full-floating pin end for superior wrist pin support and lubrication
• 3/8 WMC Rod Bolts (H11 Tool Steel): Features asymmetrical threads for evenly distributed thread engagement, increased clamp load, and improved fatigue life — rated at 220,000 PSI UTS
• Proprietary Carrilloy Steel: Manufactured from CP-Carrillo's exclusive 4330M chromoly steel alloy — a chrome, nickel, molybdenum, vanadium blend meeting VAR (Vacuum Arc Re-melt) ASTM standards, 22% stronger than traditional 4330M
• Forged from Oversized Blanks: Ensures proper grain flow and guaranteed removal of surface inclusions for consistent, reliable strength
• Multi-Stage Quality Inspection: Each rod is magnafluxed twice, Rockwell tested to validate heat treatment, and receives a controlled shot peen operation to relieve tensile stress and improve fatigue life
• Laser-Marked for Traceability: Each rod is individually serialized for full traceability and quality assurance
• Made in the USA at CP-Carrillo's manufacturing facility in Irvine, California

Each set ships with CP-Carrillo's specified assembly lubricant and detailed torque/stretch specifications. Important: Install bolts using the stretch method per the included instruction sheet. Do not use an impact gun to start rod bolts. Rod cap and beam should be numbered prior to disassembly to ensure proper matched assembly.
