It's a 1" impact that generates 1400 ft lbs of torque if operating under ideal conditions. I don't think I could exert that much force with a total of 6' of leverage.

The torque spec on the lug nuts is around 380 lbs. I'm hoping that once I get them loosened, I can retorque them and they will be capable of being loosened with a 40" breaker bar since I don't want to haul around a compressor and 40 lbs of impact wrench just to change a tire and wheel.
