Vehicle Fitment

• 1988-2002 Honda Accord (CB/CD/CF/CL/CG series) - F20A, F22A, F22B series (2.0L/2.2L SOHC Inline-4)
• 1987-2001 Honda Prelude (BA/BB series) - B20A, B21A (2.0L DOHC), F20A (2.0L SOHC), F22A, H22A, H22Z (2.2L DOHC VTEC)

• 1988-1995 Honda Prelude 2G/3G - B20A/B20A series (1.958L DOHC Inline-4)
• Various Honda Inspire, Vigor, and Accord-based platforms with F20A or F22A/B engine codes

Fitment Notes

• This bearing set covers a broad family of Honda inline-4 engines sharing identical crankpin journal dimensions: B20A/B20A variants (1958cc DOHC), B21A/B21A1 (2056cc DOHC), F20A variants (1997cc SOHC), F22A variants (2156cc SOHC), F22B variants (2156cc SOHC), F22C1 (2157cc DOHC - S2000), H22A variants (2157cc DOHC VTEC), H22Z1, and H23A.
• Standard (STD) crankshaft rod journal diameter - for use with stock or unworn crankpins at factory diameter only. For reground crankshafts, use 4B1936H-.025 (+0.025mm) or 4B1936H-.25 (+0.25mm) as appropriate.
• Always measure crankshaft rod journal diameter with a micrometer before selecting bearing size. Confirm actual clearance with Plastigage or a dial bore gauge after assembly.
• Sold as a complete set of 8 bearing shells - sufficient for one full 4-cylinder engine build.

Features

• Tri-metal construction: copper-lead alloy lining bonded over a hardened steel backing, with a high-strength overlay plate - engineered for the performance rebuild and high-RPM demands of the Honda F and H engine families.
• Hardened steel backing on all rod bearings improves structural support of the bearing lining and maintains crush under high sustained loads and temperatures.
• High-strength overlay plate with reduced thickness provides improved fatigue resistance compared to OEM-spec bearings - important in naturally aspirated and forced-induction F/H-series builds at elevated power levels.
• Increased bearing crush and tighter wall tolerances ensure consistent, secure seating in the connecting rod housing bore, reducing the risk of bearing spin.
• Enlarged ID chamfers on bearing edges accommodate the larger fillet radii found on performance and aftermarket Honda crankshafts.
• 3/4-groove design optimizes oil supply to the rod journal and maximizes load-carrying surface area across the bearing face.
• Elimination of flash plating on bearing backs improves heat transfer and maximizes grip between the bearing shell and the rod housing bore.
• Increased eccentricity compensates for bore distortion at high RPM and assists in the formation of a stable hydrodynamic oil film under load.

Product Description

The ACL Race Series 4B1936H-STD connecting rod bearing set is the standard-size performance replacement for one of Honda's broadest inline-4 engine families - spanning the B20A/B21A DOHC engines of the late-1980s Prelude, the F20A and F22A/F22B SOHC engines of the Honda Accord through multiple generations, and the high-performance H22A DOHC VTEC engines powering the Prelude Type S and Accord Type-R. All of these engines share identical crankpin journal dimensions, allowing a single bearing set to serve them at standard crankshaft size.

Built on ACL's Race Series tri-metal platform, these bearings deliver superior fatigue resistance, bearing retention, and oil film stability over OEM Honda shells - a reliable upgrade for any F or H-series engine rebuild, from everyday Accord refreshes to high-performance Prelude and Accord Type-R builds. Always confirm clearances at assembly. Sold as a complete set of 8 shells for one engine.
