Carrillo SCR5353-4 Pro-SA Forged Connecting Rods

Part of CP-Carrillo's renowned Pro-SA series, these rods occupy the middle ground between the heavy-duty Pro-H H-beam and the lightweight Pro-A A-beam, delivering an ideal balance of strength and reduced rotating mass.

Key Features:

• Pro-SA Super A-Beam Design: Increased beam thickness over standard A-beam rods to handle higher cylinder pressures and load capacities while minimizing weight
• Proprietary Carrilloy Steel: Manufactured from CP-Carrillo's exclusive chrome, nickel, molybdenum, and vanadium alloy that meets VAR (Vacuum Arc Re-Melt) ASTM standards for exceptional fatigue resistance
• Precision Forged Construction: Each rod is forged from oversized billets to ensure proper grain flow and eliminate surface inclusions generated during the forging process
• 3/8 WMC Rod Bolts: Equipped with Carrillo's high-strength WMC fasteners, jointly designed and patented by Carrillo, featuring a proprietary thread design for maximum clamping force
• 20mm Full-Floating Wrist Pin: Bushed pin end with a full-floating pin configuration for superior lubrication and reduced wear
• Rigorous Quality Control: Each rod is magnafluxed at least twice during production and Rockwell tested to validate the heat treat procedure, then finished with a controlled shot peen operation
• CNC Machined to Tight Tolerances: All critical CNC machines are equipped with probing to accurately validate dimensional integrity throughout the manufacturing process
• Laser Serialized: Each rod receives a laser-engraved job number for full traceability
• Made in the USA: Manufactured at CP-Carrillo's headquarters and plant in Irvine, California

The Carrillo Pro-SA series is well-suited for forced induction and high-revving performance builds where both strength and rotating mass reduction are critical priorities.
