Main and Rod Bearing Set +0.50mm Porsche Panamera Macan Cayenne 3.0L EA839 9A710556100

Severe engine bearing wear in the high-performance Porsche EA839 V6 engine is often the result of oil starvation, extreme thermal stress, or high-boost applications, leading to significant scoring on the crankshaft journals. When a crankshaft requires professional machining to restore its surface, standard bearings no longer provide the necessary oil clearance. This +0.50mm (+0.020in) oversized main and rod bearing set is specifically engineered to accommodate a ground crankshaft, restoring factory-spec oil pressure and bottom-end stability. Manufactured with high-strength materials, these bearings ensure the engine can reliably handle the torque demands of the Panamera and Cayenne while preventing future metal-to-metal contact and catastrophic failure.
