ACL Race main bearings for Honda F20C / F22C

ACL Race main bearings are trimetal engine bearings designed for higher loads and increased RPM conditions. Their construction combines a high-strength overlay plate with reduced thickness and tight, consistent wall tolerances.

Increased eccentricity helps compensate for bore distortion at high RPM and assists in forming a hydrodynamic oil film. The set includes ACL Race Series main bearings.

• High-strength overlay plate with reduced thickness
• Increased crush for improved bearing retention in the housing
• Elimination of flash plating on the back for improved heat transfer and grip in the housing
• 3/4-grooved main bearings to optimize load-carrying surface area and oil flow
• Tight, consistent wall tolerances
• Enlarged ID chamfers for large fillet radii on performance crankshafts

Suitable for: Honda S2000 I (AP).

Engines: F20C, F22C (F20C1, F20C2, F22C1). Please check your vehicle’s engine code (registration document or VIN) before ordering; if in doubt, contact us and we will check for you.

Sizes

STD is the standard size for an unground crankshaft. Undersizes (−0.25 mm, −0.50 mm …) are for a reground crank, and “+0.025 mm clearance” (X) is for highly stressed engines. Your machine shop chooses the size after measuring.
