19-spline coupler
Direct factory motor replacement
Navitas controller compatible

NOTE: Performance gains require an upgraded controller and properly maintained mechanical components.
This motor is engineered to work with stock factory controllers and aftermarket controllers programmed with a custom, motor-specific field map. Using an incorrectly programmed controller may result in motor damage and will void all warranties.
Break-In Procedure:
Step 1 – Initial Drive: Drive the vehicle for 8–10 miles at varying speeds, accelerating gently throughout.
Step 2 – Temperature Monitoring: Drive on a level surface (pavement or asphalt). Gradually accelerate and maintain full speed for 5–10 minutes, then stop and check motor temperature.
During the first 30 minutes, check temperature every 10 minutes by touching the aluminum end bell (silver component near the center of the motor).
If the end bell is too hot to touch, stop and allow the motor to cool before continuing.
If you can hold your hand on it for 5+ seconds, it is safe to continue for a few more miles. Repeat until the 8–10 mile break-in is complete.
CAUTION: Avoid touching any exposed electrical connections while power is on.
NOTE: Speed and torque will improve as brushes seat against the commutator. A cooler-running motor is a more efficient motor.
