I have a 84 Ranger with the 2.8 that used to turn 36x14.50x15 SuperSwamper TSL Radials. And it actually did good in the mud and such. I could get 65 on the highway when it was flat. But it hated hills and I couldn't keep anything above 50 on steep hills and had to always down shift into 3rd to even attempt that. I am not sure what gears I have in it. It was built when I bought it in 2001, and I haven't had any reason to pull the difs yet? I did have a problem breaking lug studs every few months, In the beginingm I would change each lug stud on that hub, but after awhile, I would just replace the broken once. Howeer, I have blown the motor now. And the odometer only show 64,000 miles. I know it isn't entirely acurate, due to it never being recalibrated after the new tires, but It is still premature for the motor regardless. But then again, I wasn't worried about blowing the motor either. Ever since I bought it, I had plans of dropping a 351W into and new that I would never get around to it with it still running. And while I didn't try to blow the motor on purpose, I back off it much either. It did great in the mud, and rarely did I ever have any complaints about it. Now I am just waiting to find a truck with a 351W, C4, and a 205 in it that I can steal everything from to get my truck up and running again. I am going to replace the whole drive train from the wingnut on the air cleaner to the axles and exhaust. Just waiting on the time and money though. Seems when I have the time, I don't have the money and vice versa. But hopefully here soon.
