5.4 Gears

I've read everyone saying that a lower gear ratio will help a 5.4 3v on its torque. I was wondering what a good ratio would be if I am running 275/75/18 tires and I don't do that much highway driving (Live in the country) and I occasionally pull a trailer. Any advice would be great.

Thanks!

I would go with 4.10 gears or 4.56 I did the swap and went with 4.56 and was happy.

Where would you say you would get the cost efficient gears? I am trying to keep this on the cheap side of things.

I used Yukon gears and did the labor myself.
