i just bought my 2001 SuperCrew 4x4 Lariat a couple months ago i have a 2.5 procomp leveling kit i need to install but i want to run 35 inch tires on my stock 17in wheels the guy at 4WP says its possible with some trimming...has anyone run this size tire with a leveling kit before??? if so any pics... thank you...

 

I ran 35's with no problem on my 02 with a 5.5" lift. It was a 2wd though. You might be ok with the 2.5 and trimming.

 

Return the leveling kit, use that money to cover the alignment after you crank the factory torsion bars for free to get level.

As for clearance, on stock wheels you'll probably scrub the frame at full lock and you'll need to trim the corner of the front bumper valence.
