I have a 2012 Nissan Titan. I'd like to upgrade the gear ratio because I pull a heavy 16 foot covered trailer for work and it's always loaded down with tools and job material. I'm also gonna be running 33 inch tires with 22 inch rims soon. The truck is very sluggish as it sits now. So my question is what gear ratio would I need to upgrade to in order to see some boost in performance. I believe I have the 2.94 gears now. At least that's what the dealership told me it had in it.

You can upgrade to the 3.36 gearing, just remember if you are 4wd you need to do the front and rear. I don't know what year they switched to 35 spline from the 32, but that seems to be the cut off for many options.
