Vehicle Compatibility

| Model | Compatible Versions | Drive System |
|---|---|---|

Installation Tips
- Apply a small drop of blue threadlocker (e.g., Loctite 242) to the mounting bolts — vibration can loosen them over time.
- After installation, verify the chain has approximately 1/4" of vertical slack. Over-tightening causes friction, reduces top speed, and can overheat the motor.
