Description
ACL Performance Race Series main bearing sets deliver everything performance bearings should be by utilizing design, metallurgy, engineering, precision quality control, and of course, years of knowledge and experience.
Main bearings feature multi-layered tri-metal copper alloy construction that blends characteristics to provide high strength and excellent seizure resistance. They are manufactured to exact tolerances ensuring a reliable fit and helping to maintain consistent clearances. Main bearings are augmented with extended grooves, as well as other bearing enhancements, like increased crush, bearing eccentricity, and enlarged I.D. chamfers.
ACL Performance Race Series main bearing sets are produced in standard and extra clearance versions, with or without friction reducer coating, and with modifications to meet specific build requirements, such as narrowed bearings that permit additional edge clearance when running crankshafts with exceptionally large fillet radii.
In the heat of competition proven technology always comes through. The choice for your build should always be ACL Performance Race Series engine bearings. Choose the main bearing set designed for your vehicle.
Product Overview
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, 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.
* *3/4 grooved Main Bearings* to optimize bearing load carrying surface area and oil flow to the conrod bearings.
* *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.
