Connecting Rod Bearing Set +0.50mm Toyota GR Supra 3.0L B58 13281WAA01

Severe wear on the connecting rod bearings of the B58 engine is typically caused by oil starvation during high-G maneuvers or extreme thermal stress in tuned, high-boost applications. This wear often results in "rod knock" and significant scoring on the crankshaft journals. When a crankshaft requires professional machining to restore its surface, standard bearings no longer provide the necessary oil clearances. This +0.50mm (+0.020in) oversized rod bearing set is specifically engineered to accommodate a ground crankshaft, restoring the critical oil film thickness and bottom-end stability. Manufactured with advanced high-strength alloys, these bearings ensure the engine can reliably handle the high torque output of the GR Supra while preventing future metal-to-metal contact and catastrophic engine failure.
