The ACL 4B8296H-STD Rod Bearing For Subaru EJ20/EJ22/EJ25(Suites 52mm Journal)

The main bearings in your engine take a lot of abuse. A quality set of bearings will keep your engine running better longer. The unique combination of design, metallurgy, and engineering come together to deliver what engine builder expect from a high performance Trimetal engine bearing. Designed to withstand higher RPM conditions, ACL Race Series Connecting Rod Bearings are available for many of the popular 4, 6 & 8 cylinder applications and feature: 
* *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.
