Description
ACL Performance offers Race Series rod bearing sets for a wide range of vehicles. These high performance tri-metal engine bearings are designed to withstand higher RPM conditions. They feature a high-strength overlay plate with reduced thickness for improved fatigue properties. Select the crankshaft undersize and quantity recommended for your year/make and engine application.
Additional details:
* 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 in. 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
