It's funny how much discretion the dealership has. I have 2 dealerships close to me, one is huge, has experienced techs and advisors..and the other one is smaller and doesn't even service HDs, all their techs are 19-20 year olds that are apprentices from local auto schools.
I had a torn CV boot. The small dealer blamed it on the levelling kit and said..in not so many words..that levels are satan's creations. The larger dealer, a little further up but worth the drive was along the lines of, "yes, this part # is covered under warranty. Is the front lifted? looks sweet"
