Construction & Design:
ACL rod bearings are crafted using a tri-metal construction that typically includes a steel backing, a copper-lead intermediate layer, and a soft overlay designed to embed debris and prevent scoring. This combination offers a balance of strength, durability, and conformability to the connecting rod journals. The bearings undergo rigorous dimensional inspections and surface finishing to guarantee smooth operation and long service life.
The design focuses on maintaining optimal oil film thickness, which is critical for reducing metal-to-metal contact and minimizing wear. This ensures that the bearings perform reliably under the high thermal and mechanical stresses encountered in the Toyota GR Supra’s turbocharged inline-six engine.
Installation & Fitment:
The ACL Performance Rod Bearing Set is a direct replacement for the factory bearings in the 2020 Toyota GR Supra with the BMW B58B30 and S58B30 engines. Installation requires standard engine disassembly procedures, including removal of the connecting rods and crankshaft inspection. It is recommended to measure bearing clearances with plastigage or a micrometer to confirm proper fitment and oil clearance.
No modifications to the engine block or rods are necessary, making this bearing set a straightforward upgrade or replacement during engine rebuilds or performance enhancements.
What's Included:
- Complete set of connecting rod bearings sized for standard journal dimensions
- Installation instructions and specifications for oil clearance
Ideal For:
