ACL Tri-Metal Main Bearings (’92-’96 7 Bolt DSM 4G63)

Description ACL Race Series Performance Engine Bearings The unique combination of design, metallurgy and engineering come together to deliver what drivers expect from high performance Tri-metal engine bearings. Designed to withstand higher RPM conditions, ACL Race Series Engine 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 bearing sand 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 con-rod 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. -Sold in standard size, if another size is needed please note it in the comments section
