Before You Order
GEM motor compatibility depends on more than the vehicle model name. Before ordering, please verify:
- Your vehicle is a GEM car
- Your current motor uses a compatible 19-tooth Dana spline
- Your motor cross-reference matches one of the listed compatible numbers
- Your controller and wiring are compatible
- Your batteries, controller, solenoid, cables, and wiring are in good condition
- You understand that higher-speed performance may require controller reprogramming
If you are not sure which motor your GEM needs, contact us before ordering. Photos of your existing motor tag, motor spline, controller area, battery setup, and vehicle information can help us confirm the correct replacement.
Important Performance Notes
This motor can provide strong performance in compatible GEM applications, but final speed and acceleration depend heavily on the rest of the vehicle setup.
For higher performance levels, including 30+ MPH potential, controller reprogramming may be required. Battery condition, tire size, controller setup, vehicle weight, terrain, and overall mechanical condition all matter.
Shipping Note
Motors typically ship within 5–10 business days from the manufacturer.
Shipping times may vary based on manufacturer availability, production schedules, and order volume.
