I don't have it handy but there are differences. 1. the ujoints and driveline are heavier to the main gearbox. the clutch is a four disc instead of a three disk. the reversing gearbox heavy duty drive is standard. the rear axle is heavier. it comes with larger standard rear tires. and there is something else but i don't recall. also standard heavy lift cylinders and heavy duty final drives. if you option a 9650 to handle 12 row the difference is only seven grand or less.
