I went across the rubicon form loon lake to buck island on 6 inches of lift 33's with ifs twice with no breaks what so ever the first time no damage second time was not so nice....
I was with jeep unlimiteds on 37's with hemi swaps and they were breaking my IFS yota was like a rock, third time she may break something lol, but the whole front end is brand new axels, ball joints, LR ucas, and new 886s so crawls good 35s would help a lot more though

what do you have done on your FJ?
i want to straight axel my rig, but I don't want to cut into the frame, going to get he back to as perfect and mint as possible keep her a pavement pounder and get a fj45 or possible unimog axle swap onto a 97 tacoma 4dr with flat bed
