what all would i need to remove the 6" lift off and return it to level height. I like the lift but it would be easier to tow stuff with less height. I have 2012 Ram 2500

 

Tools. You would need tools. Jack stands (or a lift), impact wrenches would be a good idea. Penetrating fluid on the fasteners. Good lighting. Safety glasses, don't forget those. If you have oversized wheels/tires, you probably will need to go back to stock size there too.

 

I got the tools. can i just switch the lift kit out for a leveling kit?

 

Yes. You would need all the stock hardware and fasteners that might have been removed to install the lift. Example, if you have a 6" block on the rear, you would need the original u-bolts once you remove the blocks.
