Royal Enfield 570535/H – Exhaust Rocker Arm OEM for All UCE Models (Classic 350/500, Bullet 350/500, Thunderbird 350/500 & Continental GT 535)

The genuine Royal Enfield 570535/H Exhaust Rocker Arm is designed for all UCE engines — both 350 cc and 500 cc platforms. This rocker arm sits on the exhaust side of the cylinder head and transfers camshaft motion through the pushrod to the exhaust valve, ensuring correct valve lift, timing, and sealing.

Made from hardened steel with a precision-ground contact pad, it resists wear and maintains smooth valve train operation even under high heat and pressure. If your UCE bike is showing valve noise, tapping sounds, or reduced performance, replacing the exhaust rocker arm with OEM 570535/H restores factory-spec valve actuation and reliability.

This part is confirmed across Classic 350/500, Bullet 350/500, Thunderbird 350/500, and Continental GT 535. Installation involves removing the rocker cover, checking pushrods and pivots, and torquing the rocker arm to service manual specifications. OEM quality ensures durability and reduces the risk of valve train failure compared to aftermarket copies.

FAQs:

1. Does 570535/H fit both 350 cc and 500 cc UCE bikes?
   → Yes. It is confirmed across all UCE models including Classic, Bullet, Thunderbird (350 & 500) and Continental GT 535.

2. What’s the difference between exhaust and inlet rocker arms?
   → Exhaust rocker arms like 570535/H are shaped for higher load and heat, while inlet rocker arms have different geometry and a separate part number.

3. What are the signs of a failing rocker arm?
   → Tapping noise from the cylinder head, poor idle, reduced compression, or visible wear at the rocker pad or pivot.

4. Should I replace inlet and exhaust rocker arms together?
   → It’s recommended if both show similar wear, though you can replace just the faulty one.

5. Why OEM instead of aftermarket?
   → OEM rocker arms ensure correct metallurgy, wear resistance, and geometry. Aftermarket parts often cause misalignment, excess wear, or valve train failure.
