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

Severe engine bearing wear in the B58 platform is often the result of oil starvation during high-G cornering or extreme thermal stress in high-boost applications, leading to deep scoring on the crankshaft journals. When a crankshaft requires significant machining to restore its structural integrity, standard or minor oversized bearings are insufficient. This +0.50mm (+0.020in) oversized bearing set is engineered to provide the exact oil clearance required for a heavily ground crankshaft, restoring factory-level oil pressure and rotational balance. Built with high-strength multi-layer materials, these bearings ensure the engine's bottom end can handle the torque demands of the GR Supra while preventing future metal-to-metal contact and catastrophic failure.
