SHould have been SWAG. scientific wild assed guess......
I noticed the change in my truck from a 31.5 to 32.5 tires. Also 10 lbs heavier! Latter is probably the biggest part. Then I only have a 4.3 V6. Raised it 2". I'm now about a 3.2 effective vs the 3.42 stock. Even at that, It does good. Lost 1-2 mpg tho.....
If you can not get bars correctly connected to come home/get somewhere etc. I would not worry too much. With 40 years pulling with 8 lug 25/35 series trucks. I found it took 500+ lbs of weight off the front axel to effect how it felt etc. That is around 1500-2000 lbs of HW for a crew cab 170'ish inch WB. 6400 lbs rear springs. With 8500 springs, typical of duallys a decade back, then it was 2000+ lbs of HW to really effect the steering etc. my Reg cab 2500's was more in the 1000-1200 lbs relm. This is stock setups. You being lifted, taller tires. I'm not going to say my experience is equal.
