The aftermarket tie rods wont change the geometry of the front suspension unless there is some kind of offset built into the tie rod ends.  The easy way to check is to see if the tie rods are parallel to the lower a arms.  I compared my zilla to my yfz when i did mine. I try to get some pics posted to show you what im talking about.  I just have to hobble my ass down to the shed to look.  I was supposed to be riding all weekend but i fell 16 feet onto concrete and shattered my ankle last week.  Looks like ill be on here a lot for the next month or two. Lol
