ACL High Performance Main Bearing Set 0.25mm Oversized for Select Acura/Honda/Isuzu 1986-2005 - 5M1957H-.25
$138.87
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1986-2005 Acura, Honda, and Isuzu models including Integra, Accord, Civic, and Prelude (D16A1 / H22A4 / F23A engines).
Engineered for high-RPM and high-load applications, the ACL Race Series main bearing set is a critical upgrade for performance engine rebuilds. This 0.25mm oversized set is specifically designed for engines where the crankshaft journals have been machined or ground 0.25mm undersize to restore proper clearances and surface finish. Unlike standard replacement bearings, these feature a high-strength tri-metal construction capable of withstanding the rigors of forced induction or competitive track use.
- Manufacturer Part Number: 5M1957H-.25
- 0.25mm Oversized (for .25mm undersized crankshaft journals)
- Hardened steel backing for improved bearing support and retention
- Increased crush for maximum shell-to-housing contact
- Large chamfers to accommodate performance crankshaft fillets
- Compatible with D16A1, H22A4, and F23A engine blocks
