The Artec truss both front and rear come in under $500. This sounds like pretty cheap insurance to me. None of the axles are bombproof. It is a luck of the draw. You may get lucky and bang it over rocks all day and just get wear items - or you could be the lucky one who just happens to hit a deep pothole the wrong way with enough force to grenade it. Do you feel lucky?
