Construction & Design:
The bearings feature a tri-metal construction that combines a steel backing with layers of copper-lead and a babbitt overlay, providing a balance of strength, conformability, and embeddability. This design ensures the bearings can accommodate slight misalignments and debris without compromising engine integrity. The pMax Black coating further enhances the bearing surface by reducing friction and resisting wear, which contributes to longer service life and improved engine efficiency.
Manufactured to exacting tolerances, these bearings maintain consistent thickness and roundness, critical for maintaining proper oil clearance and preventing premature failure. The .025 oversize dimension is tailored for engines that have undergone journal machining or require a larger bearing to maintain optimal clearances.
Installation & Fitment:
Installation of the King Engine Bearings Tri-Metal Performance Rod Bearing Set is straightforward for experienced mechanics and engine builders. These bearings are designed to fit the connecting rods of Subaru BRZ models from 2013 to 2017 and Toyota 86 models from 2017, specifically those with 52mm journal diameters requiring a .025 oversize bearing. Proper measurement and clearance checks are essential to ensure correct fitment and optimal performance.
No modifications to the engine block or rods are typically necessary when installing these bearings, but it is recommended to follow manufacturer torque specifications and use proper assembly lubricants during installation. This ensures the bearings seat correctly and function reliably from the first start.
