Show original supplier description
The ACL 4B8310H-STD is a high-performance rod bearing set engineered for enhanced engine durability under demanding conditions. Constructed with a Trimetal design, these bearings are specifically built to withstand higher RPM ranges, making them suitable for performance applications. They feature a high-strength overlay plate with a reduced thickness to improve fatigue properties and ensure longevity. These rod bearings also incorporate hardened steel backs, which enhance the support of the bearing lining and aid in bearing retention within the housing. The design includes increased crush for improved retention and eliminates flash plating on the back of the bearings to optimize heat transfer and maximize grip between the bearing and its housing. Furthermore, increased eccentricity is incorporated to compensate for bore distortion at high RPMs and to assist in forming hydrodynamic oil films. For optimal performance, the main bearings are 3/4 grooved to maximize bearing load-carrying surface area and oil flow to the conrod bearings. This specific model, the 4B8310H-STD, is a standard size connecting rod bearing set. It is compatible with Subaru BRZ models from 2013-2021, Scion FR-S models from 2013-2016, and Toyota 86 models from 2017-2021, all equipped with the FA20 engine. Available sizes include STD, .025, and .25.
