The ACL Main Bearing set provides the dependability that drivers expect from high performance tri-metal engine bearings. ACL Race bearings have a unique combination of design, metallurgy and engineering that ensures they can withstand higher RPM conditions/applications.

Features:

- High strength overlay plate with reduced thickness.
- Hardened steel backing to maintain crush under high loads and temperatures.
- Increased crush and elimination of flash plating.
- Tight consistent wall tolerances.
- Large chamfer to accommodate larger crankshaft fillets.
- 3/4 groove main bearings to optimize bearing load carrying capacity and oil flow to rod bearings.
- For Evo models V - IX.
- Extra oil clearance is available over base model for harder race applications.
- .025 Oversize is available over base model to allow for re-ground cranks.
- .25 Oversize is available over base model to allow for re-ground cranks.
