Eagle CRS5531A3D-1 H-Beam Connecting Rod Honda B-Series 5.531"

The Eagle CRS5531A3D-1 H-Beam connecting rod is engineered for high-performance Honda B-series engines, offering exceptional strength and durability for turbocharged, supercharged, and high-RPM applications. This 5.531-inch rod length is specifically designed for Honda B18C1/C5, B20B/Z, and B18A/B engines, providing an ideal upgrade path for racers and enthusiasts seeking to exceed factory power limits.

Advanced Manufacturing Process:

• Forged from certified 4340 chromoly steel in a two-piece forging process
• Vacuum-degassed for superior material consistency and strength
• Multi-stage heat-treated for optimal hardness and fatigue resistance
• X-rayed, sonic-tested, and magnafluxed to ensure material integrity
• Shot-peened to stress-relieve the metal and extend service life
• 100 percent CNC-machined for precise tolerances

Premium Components:

• ARP 2000 series 3/8-inch rod bolts for exceptional clamping force
• Precision cap alignment sleeves for positive rod cap location
• Silicon bronze bushings designed for floating pin applications
• Weight-matched set to ensure smooth engine operation
• Advertised weight: 520 grams per rod

These H-beam connecting rods are recommended for engines producing up to 900 horsepower in four-cylinder turbocharged applications, making them suitable for serious street, strip, and road racing builds. Eagle's proprietary 4340 steel formulation routinely tests 10-15% stronger than standard SAE/AISI spec 4340 steel through tighter control of alloying elements including enhanced nickel and chrome content.
