Main and Connecting Rod Bearing Set +0.25mm Toyota GR Supra 3.0L B58 13281WAA01

Over time, the high-performance B58 engine in the GR Supra can experience significant bearing wear due to high boost levels, oil starvation during spirited driving, or extended service intervals, often resulting in rod knock or crankshaft scoring. When the crankshaft journals require professional machining to restore a smooth surface, standard bearings will no longer provide the necessary oil clearance. This +0.25mm (+0.010in) oversized bearing set is specifically engineered to accommodate a ground crankshaft, restoring factory-spec oil pressure and bottom-end stability. Manufactured with advanced high-strength materials, these bearings offer superior fatigue resistance and load-carrying capacity, ensuring a reliable engine rebuild and protecting the crankshaft from future catastrophic failure.
