You can remove the air dam fairly easily (at least on the 4x4s) that would be cheaper and easier than levelling the truck. If you do want to level it though I wouldn't go more than 2"

The air dam helps a little with fuel mileage, but those that have removed it have posted that it didn’t make a huge difference.

For free, you could just remove it and see how you like it. Then, you always have the option of putting it back on.

I have also seen a post where someone cut about half of it off, so it wasn’t as big.

You can go 2.5 on a 2wd with no issues. I would with a 275/70/18 (33.2”) on the stock wheels. You can go as big as 295/7018 (34.3”) on the stock wheel, but you would need this kit along with some quality 1.25” spacer for the front wheels to clear the new upper control arms.

If you Google the part number from this kit, you can find it for significantly less than the list price

wheel spacers

You wont need back spacers. As the front suspension drops, it pulls the front wheels inward. The 1.25” spacers will put them on line with the rear wheels.

That’s as big as you can go on cactory wheels without buy a significantly more expensive kit that requires frame cutting. Your 2wd will look like a leveled 4x4 when you’re done.

Nice looking truck BTW, I like the grey grill with that color.
