If you’re pushing your Ford Focus or Focus ST to the limit, you need engine bearings that can keep up with your performance demands. The ACL Race Series Engine Bearings (part number 4B4390HX-STD) are engineered specifically for high RPM conditions, making them a must-have for those who take their driving seriously. These bearings are designed to handle the rigors of racing and spirited driving, providing reliability and performance when you need it most.

Features

High-strength overlay plate with reduced thickness enhances fatigue resistance for long-lasting durability.
Hardened steel backs on all rod bearings improve support for the bearing lining and ensure secure retention in the housing.
Increased crush for superior bearing retention, giving you peace of mind during high-stress situations.
Elimination of flash plating on the back of the bearings maximizes heat transfer and improves the grip between the bearings and housing.
Increased eccentricity helps compensate for bore distortion at high RPM, aiding in the formation of hydrodynamic oil films.
3/4 grooved main bearings optimize load-carrying surface area and oil flow to the connecting rod bearings.
Tight and consistent wall tolerances help maintain precise clearances for optimal performance.
Enlarged ID chamfers on bearing edges accommodate larger fillet radii found on performance crankshafts.
