Construction & Design:
ACL rod bearings are constructed using advanced tri-metal materials that combine a steel backing with layers of copper and a soft overlay to provide excellent conformability and embedability. This design helps protect the crankshaft journal from damage caused by contaminants and ensures a stable oil film under high load conditions. The .025mm oversized sizing allows for precise fitment when the crankshaft journals have been machined or polished, maintaining optimal bearing clearance and oil flow.
The bearings undergo rigorous quality control processes, including dimensional checks and surface finish inspections, to guarantee consistent performance and longevity. This attention to detail ensures that the bearings can handle the stresses of high-revving engines and aggressive driving styles without compromising reliability.
Installation & Fitment:
The ACL Rod Bearing Set is a direct fit replacement for the FA20 engine in the specified Toyota 86, Subaru BRZ, and Toyota GR86 model years. Installation requires standard engine disassembly procedures and should be performed by a qualified technician or experienced enthusiast. Proper measurement of crankshaft journal diameter and bearing clearance is essential to ensure the correct oversized bearing size is used.
No additional modifications are typically necessary when installing this bearing set, but it is recommended to inspect the crankshaft and connecting rods for wear or damage during installation. Following manufacturer torque specifications and lubrication guidelines will help achieve optimal bearing performance and engine longevity.
