can i put a lift on my truck?

Ah, Grasshopper- it will cost many wagons laden with gold and silver- but this is a small price for the experience of riding serenely above the common people, the unwashed, those who do not understand- ride the sky beast and worry not about the cost

you could put that much lift on it. it will require a lot of custom fabrication. cost would depend on the shop you chose to do it. I would ask around of owners of lifted trucks in your area for a reference to a reputable shop. good work is not cheap.
