Carrillo SCR4248-1 Pro-H Beam Connecting Rod Honda Acura K24 Single

The Carrillo SCR4248-1 is a single Pro-H beam connecting rod engineered for Honda and Acura K24 series engines used in high-performance street and motorsport applications. Sold individually, this rod is the same race-proven component found in the SCR4248-4 set, allowing builders to replace a single rod without purchasing a full set.

Carrilloy Proprietary Steel Construction:

• Manufactured from Carrillo's proprietary Carrilloy alloy — a chrome, nickel, moly, vanadium blend meeting all VAR (Vacuum Arc Re-Melt) ASTM standards
• Forged from oversized stock to ensure proper grain flow and eliminate surface inclusions
• Mar-aged heat treatment process delivers 195,000 UTS and 182,000 PSI yield strength while maintaining critical low notch-sensitivity and ductility

Precision Manufacturing & Quality Control:

• All critical CNC machining operations use integrated probing to validate dimensional integrity
• Each rod is magnafluxed at least twice during production to identify any surface flaws
• Individual Rockwell hardness testing validates the heat treat procedure on every piece
• Final controlled shot peen operation improves fatigue life by replacing tensile surface stresses with beneficial compressive stresses
• Job number laser-etched on each rod for full traceability

CARR Bolt Fastener System:

• Includes Carrillo's proprietary CARR bolts (Multiphase MP35N, 285,000 UTS) — a significant upgrade over standard ARP2000 fasteners
• Patented thread design with the highest dimensional integrity in the industry
• Each fastener lot is destructively sample-tested for ultimate tensile strength and fatigue resistance

Built in the USA at Carrillo's Irvine, California facility, the SCR4248-1 delivers the same race-winning quality trusted across virtually every form of motorsport — from drag racing and road racing to oval track and off-road competition.
