Club Car IQ 48V 500A Controller Conversion Kit — FX503G021K (Stock Motor)

The FX503G021K is a 48V 500A controller conversion kit for Club Car IQ-platform golf carts with the stock OEM motor. The 500A controller is a significant upgrade over the factory unit — delivering dramatically better throttle response, acceleration, and hill-climbing even with the stock motor.

Key Specifications

Voltage: 48V DC
Controller Current: 500A
Motor Compatibility: Stock Club Car motor
Fitment: Club Car IQ 48V golf carts
Part number: FX503G021K

Applications

Major controller upgrade for 48V Club Car IQ golf carts using the stock motor. The 500A rating provides a massive current increase over the factory controller — more power to the stock motor for better performance on hills, with loads, and from a standing start. Includes all necessary wiring and hardware. A stepping-stone upgrade before adding an aftermarket motor later.
