I have a body lift with 31's on my x right now, but Oct 1 I am putting a 6" sus lift on. Would I have to do any trimming to put 35's on? Should I just go with 33's until I get the fenders from Perry's? And will my stock gears be ok for the time being with 35's? Really need the advice.

Try a search. This question comes up quite often. Yours may be a little different, but you will see that people have fit 35s with a body lift, trimming and shackles.
