@Athena look at Thurens kit’s, I wouldn’t suggest with tampering with the stock suspension too much as that’ll lead to lot’s of money and maybe some result’s you don’t like. You can opt for his Front upper/lower standard control arms which will get your front axle back forward 1/2” which will help with rub. I would also throw his adjustable front Track bar as it is much more robust and stops a ton of deflection.
I run both of these items on My 12. He also makes a rear track bar which is a beefier than stock unit. Maybe a steering stabilizer from him, either King or something else top shelf.
Also look at the different wheels AEV sells their 17” Salta wheels for about 150 each and they have an almost perfect offset for the Power Wagon. Some people hate ‘em but you can have them painted.
You have 2” inches of lift with the 37’s over the stock 33’s. Besides you really don’t want the truck sitting too high especially off road.
So far as doing any fender liner mods you should be able to get away with a heat gun and molding the lateral ridge that covers the pinch weld that way. And if needed they square bump above the pinch weld covers a body harness and you do have some room to make that a little flatter also.
