ACL Bearings are a top choice for engine builders especially for high-horsepower builds.   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.   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.   Specifications: - Race / Performance - Standard Size Rod Bearing Set   Fitment: 2015-2021 Subaru WRX 2013-2021 Subaru BRZ 2017-2021 Toyota 86 2013-2016 Scion FRS 2013-2020 Subaru XV Crosstrek 2.0i 2012-2020 Subaru Impreza 2.0i Subaru FA/FB Engines
