Connecting Rod Bearing Set +0.50mm Audi A6 A7 A8 Q7 Q8 S4 S5 SQ5 3.0L EA839 06M105702E

Severe crankshaft wear or deep scoring on the rod journals of the Audi 3.0T EA839 engine often necessitates a more aggressive machining process. When the crankshaft journals are ground down significantly to restore a smooth, concentric surface, standard or even +0.25mm bearings will no longer provide the necessary oil clearance. This +0.50mm (+0.020in) oversized connecting rod bearing set is precision-engineered to compensate for heavily machined journals, restoring critical oil pressure and ensuring the stability of the bottom-end assembly. Built with high-fatigue resistant materials, these bearings are essential for high-performance engine rebuilds where the crankshaft has been turned to its second undersize, preventing metal-to-metal contact and ensuring long-term durability under boost.
