One often overlooked part when building an engine is the bearings. Getting a quality set of bearings can directly determine the longevity of your engine.

ACL has various types of bearings. This is their RACE bearing which is meant for engines that will be reving higher than stock, and see more abuse than they were meant to from the factory. This is a performance bearing, not a factory oem-replacement bearing.

ACL Race Series Performance Engine Bearings

The unique combination of design, metallurgy and engineering come together to deliver what drivers expect from high performance Trimetal engine bearings. Designed to withstand higher RPM conditions.

Specs:

• Half Type: Identical halves
• Material: F781
• Min. Std Shaft Size: 51.981 mm / 2.0465 in
• Max. Std Shaft Size: 52 mm / 2.0472 in
• Min. Std Tunnel Size: 55.024 mm / 2.1663 in
• Max. Std Tunnel Size: 55.042 mm / 2.1670 in
• Max Wall at Crown: 1.506 mm / 0.0593 in
• Max Overall Length: 19.3 mm / 0.7598 in

Features:

• High strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing.
• Increased crush for improved bearing retention
• Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing.
• Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films.
• Tight consistent wall tolerances to help you maintain consistent clearances.
• Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts.
