The frame extensions are only there for locating and supporting the frame during vehicle assembly - after it leaves the factory, they really have no purpose. If you nick the frame rail while cutting these off, then the dealer may be able to deny a cracked frame claim if they can show the crack propagated from the Nick, otherwise, it won’t effect anything.
