My new buddy Dan at Wheeler's Off Road in Southern Oregon said that the 5100's he has are a tiny bit longer than stockers and are good to handle 0-2" of lift. Does this sound like anything the stockers can't handle? I'm planning on purchasing just the front 5100's for now.You won't be lifting the rear more than 1.5" to level out the truck even if you lift the front a full 3" so the 5100's will work for you. I am sure Sonny or Marcos will confirm this!
If you aren't comfortable with that you could look into the 5125's 0r 5150's but then you will need adapters to get them to bolt on.
