Engine Head Rocker Arm Audi A6 A7 A8 Q7 Q8 S4 S5 SQ5 3.0L EA839 0P2109417

The rocker arms in the Audi 3.0T EA839 engine are critical components of the valvetrain, responsible for translating camshaft motion into valve opening. Early versions of these rocker arms were known for potential bearing failure, which can lead to excessive noise, misfires, and significant engine damage if the needle bearings disperse into the oil system. This updated version (0P2-109-417) features a reinforced design to provide superior durability and smoother valvetrain operation. Replacing worn or ticking rocker arms with this high-quality updated component is essential for maintaining the valvetrain integrity and high-RPM reliability expected from Audi S and SQ models.
