I agree that this is not necessary. It is also not necessary to have a 4 wheel drive truck with 600hp. The reason I like the push button rear locker is strictly for fun. Get on a gravel road, sand dune, or any low traction situation, lock up the rear end and steer with the rear. It is fun and that's it. The truck breaks without any modifications so if that is the argument, you may want to buy a hybrid Toyota, they are less likely to break and you can get really good fuel economy. I love my Raptor. My buddy has the new Dodge and it is always stuck in 4 wheel drive. He has the same problem multiplied by 2. My truck is no longer covered under warranty, so yes I get to pay to play. I have been flagged as an abusive Raptor owner, who makes all sorts of modifications, which seem to break the truck apart. The kit is really fantastic, highly recommended.
