Ok for all of that have your owners manual, there should be one in there that is called Customer Information Guide.
On page 12 ( in my book) it states that warranty can be vioded if :
"Non-Ford parts installed after the vehicle leaves Ford of Canada's control and causes a Ford part to fail. Examples include, but are not limited to lift kits, oversized tires, roll bars, cellular phones, alarm systems, remote starting systems and performance enhancing powertrain components."
sounds pretty clear to me.......but then again im going to lift it and enjoy it. Its your choice to lift and not to lift, bigger tires and what not, but just remember you might get hassled over it.
Now saying that, what if you buy the kit, have a certified Ford dealer install it, and put it on paper that they will cover any defects ? might go for that i dont know.
just crank the bars, get it even....the Alignment Tech at my dealership told me to do that, and just get it aligned.....
