ACL Race Series are trimetal engine rod bearings developed for higher RPM conditions. Their combination of design, metallurgy and engineering provides improved fatigue properties.
The bearings feature hardened steel backs, increased crush for improved retention in the housing and increased eccentricity to compensate for bore distortion and assist in forming hydrodynamic oil films. The set includes ACL Race Series rod bearings.
- High-strength overlay plate with reduced thickness
- Hardened steel backs for improved support of the bearing lining
- Elimination of flash plating on the back for improved heat transfer and grip in the housing
- Increased eccentricity to compensate for bore distortion at high RPM
- Tight, consistent wall tolerances for consistent clearances
- Enlarged ID chamfers on bearing edges for large fillet radii on performance crankshafts
Suitable for: Honda Accord V (CE/CF) / VI (CG/CH/CL), Honda Civic VII (ES/ET) / VII (EU/EP) / VIII (FD), Honda Integra TYPE (R/DC5), Honda Odyssey I (RA1/RA5) / II (RA6/RA7/RL1), Honda Shuttle II (RA).
Engines: F23A, K20A, F23Z (F23A1, F23Z5, F23A4, F23A5, F23A7, K20A3, F23Z2). 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.
