- Radialock Design: Ensures optimal crush height for precise bearing fitment and enhanced stability during operation.
- Tri-metal Copper-Based Material: Offers excellent conformability and embedability, protecting the crankshaft journal from damage.
- Precision Manufacturing: Tight tolerances and quality control ensure consistent performance and reliability.
Construction & Design:
The main bearing set is constructed using a tri-metal copper-based alloy, chosen for its excellent strength and durability characteristics. This material provides a balance of conformability and embedability, allowing the bearings to accommodate minor imperfections in the crankshaft surface while protecting it from debris and wear.
The polymer coatings applied to the bearing surfaces reduce friction and enhance load capacity, which is critical for high-performance engines subjected to increased stress. The Radialock design ensures the bearings maintain the correct crush height, preventing movement and maintaining proper oil clearance for optimal lubrication.
Installation & Fitment:
This main bearing set is designed as a direct fit replacement for the Subaru BRZ (2013–2022) and Toyota 86 (2017–2020) with the FA20 and 4U-GSE engines. Installation requires standard engine disassembly procedures and should be performed by a qualified technician or experienced enthusiast. Proper cleaning and inspection of the crankshaft journals are essential before installation to ensure maximum bearing life and engine reliability.
No modifications are necessary, and the bearings are engineered to meet or exceed OEM specifications for fit and performance.
