The Genie 37556R.S Belt Bullet Assembly is a genuine OEM replacement component for Genie belt-drive garage door opener rail systems. This assembly connects the drive belt to the opener’s trolley/carriage, providing the secure engagement needed to move the door smoothly along the rail. Replacing a worn or damaged belt bullet restores correct belt tension and consistent travel, helping eliminate slip, chatter, or erratic movement. The 37556R.S designation identifies the exact Genie part used on specific belt-rail configurations; confirm the part number in your opener’s manual or parts diagram to ensure compatibility with your Genie garage door opener.
Engineered for residential belt-drive applications, the belt bullet installs at the carriage end of the belt path. Installation generally involves disconnecting power, securing the door, releasing the trolley, relieving belt tension according to the Genie manual, swapping the old bullet at the belt end, seating the new bullet into the trolley slot, then re-tensioning and aligning the belt. After service, reprogram open/close travel limits, verify force settings, and test the safety reversing system per Genie instructions. As a mechanical component, frequency/voltage specifications do not apply. Using an authentic Genie replacement part helps maintain proper operation and long-term reliability in Genie belt-drive garage door opener systems.
