Re: What gear/axle combo to go with?

I would say you are right on the line with 33s and 3.73. It will work, but you will gain less pull than 4.10s while not eliminating all "too tall" in O/D situations. The O/D "allows" for 4.10s to be good enough for hiway while you've gained new power for your bottom end pleasure. The rigs I've had with O/D all had 4.10s with 33-35" tires. Some say 35" is too tall for 4.10s & O/D. My trucks were diesel and it worked well. What most experience with that combo is transmission "searching" between Drive and O/D with gas motors. I think that's where you would be with 3.73 & 33s. That's an excellent ratio with factory size tires. Check out that chart at Randy's for hard numbers that don't lie
