ADVICE PLEASE!

[H2 BULLY]

I have an 06 SUT. We are planning on going to Moab in Aug, and I have read the threads about the tie rods breaking. So I bought some Fabtech HD tie rods from Trailduty, and went to have the dealer put them on. They told me that if the new tie rods were to cause something else to break because they were stronger and something else might give, that it would not be covered under the warranty. So now I don't know what to do. Should I just bring them along as spares just in case or not worry about other things breaking if I put them on.
