Connecting Rod Bearing Set +0.25mm Porsche Panamera Macan Cayenne 2.9L V6 EA839 9A710570200

Over time, the high-performance EA839 engine can experience wear on the connecting rod journals due to high thermal loads or oil contamination, often leading to rod knock. When the crankshaft requires professional machining to remove scoring or imperfections, standard bearings will no longer provide the necessary oil clearance. This +0.25mm (+0.010in) oversized bearing set is specifically engineered to restore factory-spec oil pressure and bottom-end stability on ground crankshafts. Utilizing advanced metallurgical compositions, these bearings provide superior fatigue resistance and load-carrying capacity, ensuring a reliable engine rebuild and preventing future crankshaft failure.
