The Royal Enfield Valve Spring (Part No. 500309/C) is a genuine OEM engine component designed for UCE 350cc and 500cc Royal Enfield motorcycles. Located inside the cylinder head, the valve spring maintains proper valve seating and closing force, ensuring accurate valve timing, efficient combustion and smooth engine operation. It is the updated replacement for the earlier 500309/B part number.
Manufactured from premium spring steel and heat-treated for maximum durability, this valve spring is engineered to withstand high engine temperatures and continuous valve movement. It helps prevent valve float at higher RPMs while maintaining optimum engine compression and performance.
This genuine Royal Enfield replacement is ideal during engine overhauls, cylinder head repairs or valve servicing. Direct OEM fitment ensures hassle-free installation without any modifications.
