The torque output depends on the specific engine in the vehicle. The 2003 Grand Cherokee came with a variety of engine options. To give you the correct torque figure, please tell me:
* What engine is in your Jeep Grand Cherokee? (e.g., 4.0L I6, 4.7L V8, 5.7L Hemi V8)
Once you provide the engine information, I can tell you the torque output for your specific 2003 Jeep Grand Cherokee.
