Royal Enfield 574363/A – PIN-Rocker Arm OEM (2 pcs for Full Replacement) for 350 Models Classic, Meteor, Hunter & Bullet

Ensure reliable valve train performance and reduce rocker arm play with the genuine Royal Enfield 574363/A Pin-Rocker Arm. This OEM pin holds the rocker arm in position on the rocker shaft, providing the correct pivot point for intake and exhaust valves. Over time, rocker arm pins can suffer wear or damage, leading to valve noise, loose feel, or misalignment.

This part is correct OEM fit for many 350 cc models: Classic 350 (UK / Euro V), Bullet 350, Meteor 350, Hunter 350 etc., as confirmed by vendor and parts-book listings. To replace all rocker arms in the head, two pins (2 x 574363/A) are required. Because this is a load-bearing pivot pin, using genuine OEM is critical to maintain specification, reduce engine noise, and prevent excess wear on rocker arms or shafts. Before installing, visually inspect your old pin for wear, compare diameter & length, and ensure matching left/right positions.
