They will wear out like a lot of stuff on our trucks.
I bought a replacement set on ebay and had them coded for my truck so I would have an extra set on hand before they got rare and spendy.
Of course, I am so cheap I am still using the original first one since I bought the truck. Its polished and worn down to the point where I should just break out a new one but I probably won't!
