Edit cart details

Cart details are saved on this device only. Do not enter personal information here. Changing carts clears the previous configuration.

Unknown details will not be treated as confirmed.

Not sure which cart you have?

Use the vehicle label and manufacturer guidance to identify your cart. Body panels, batteries and drivetrains can be changed; a model name alone does not prove part compatibility.

Club Car

Club Car: check the barcode label below the passenger-side cup holder or above the pedals. The model letters are followed by the model-year and production-week digits. Use the manufacturer directory to confirm the prefix.

Open manufacturer identification guide

E-Z-GO

E-Z-GO: for models purchased before 2023, the manufacturer points to the steering column or below the driver-side seat. Location varies by model. Photograph the complete label, including the manufacturer code.

Open manufacturer identification guide

Yamaha

Yamaha: check under the seat at the floorboard/motor compartment, on the frame under the rear bumper, or beneath the driver-side glove box. Use the full identification label, not just the body appearance.

Park securely, set the parking brake and remove the key before looking for labels. Do not touch electrical terminals or work underneath an unsupported vehicle.
