It will probably rug the tunnel coolers. If they weren't there it would be fine. You could knotch the 1 3/4 to miss them. I put a 2 inch under mine with a U cooler. The u cooler is only about half an inch tall where the stock cooler is maybe 1 1/4. My 2 inch rubs the bottom of the tunnel itself up front some times if it gets loose but not enough to worry about.
FYI, Cat had tracks knotched from the factory to clear on some of their models.
