Vehicle Fitment

• Honda/Acura B-series Non-VTEC 1.8L & 2.0L: B18A (1990-1997), B18B (1994-2001), B20B (1996-2001), B20Z (1999-2001)

Fitment Notes

• Non-VTEC (SOHC/DOHC non-VTEC) B-series engines only; excludes VTEC variants (e.g. B18C) unless using non-VTEC head during build
• Single rod purchase - use 4 for full engine build; ensure weight matched set if replacing a full set
• Uses floating wrist-pin design; block and rod journal/pin clearances must be checked
• Torque specification with ARP moly lube on threads

Features

• Forged 4340 chromoly steel two-piece forging for high fatigue strength and durability 
• H-beam design for improved stiffness under load while optimizing weight :
• Full floating wrist-pin / bushings included for improved performance in high RPM builds
• Uses 3/8" ARP-2000 rod bolts for high strength fastener retention 
• Shot-peened, magnaflux inspected, multi-stage heat treated for consistency and strength 
• Weight matched at ~ 535 grams per rod for reduced vibration and balanced rotating assembly :
• Precise machining: tight tolerances on big end bore, pin end bore, and alignment sleeves for cap alignment, to reduce cap walk or bore distortion 
• Recommended for builds up to ~ 900 HP for 4-cylinder applications depending on supporting modifications

Product Description

The **Eagle CRS5394A3D-1** is a high-performance connecting rod designed as an individual piece for builders using Honda/Acura non-VTEC B-series bottom ends (specifically B18A, B18B, B20B, B20Z engines). Constructed from certified forged 4340 steel, this H-beam rod incorporates a two-piece forging with precision machining, shot peening, magneto flux inspection, and alignment sleeves to deliver strength for high RPM or forced induction builds. Each rod is weight matched (~ 535 g), and uses shot-peened surfaces and high quality ARP-2000 rod bolt fasteners torqued to 43 ft-lbs (with ARP moly lube on bolts) for reliable performance under stress.

Whether you're replacing one damaged rod or building a complete set, this single rod is ideal for performance Honda/Acura enthusiasts. Always inspect block condition, journal sizing, and use full floating wrist pin if required. **Fitment confirmed through 2001. 2025 unconfirmed.**
