Question:

Im looking at a hitch cargo carrier like the 63153 that has a rise shank design. Do I need to worry about the exhaust melting my cargo? Ive read comments from a few people noting that they had this issue, and I have a friend who had some bungie cords melt. But their cargo baskets may have been inline with the exhaust. I have a 2007 Mercury Mariner Premiere. My exhaust pipe shoots straight back. With the rise shank, the bottom of the basket should be above the exhaust. Probably not by much though. How much clearance is enough? Do I need to worry about the exhaust? Thanks

Exhaust melting cargo on a cargo carrier isn't a super common problem, but we are aware that it does happen on occasion. Especially if the cargo carrier is at the same height as the exhaust, relatively close to it, and/or the material in the carrier is susceptible to melting.

Other factors to consider are the size of the engine, climate, and road conditions. Engines are basically big air pumps. The bigger the motor the more hot air is pumped out of it. Hotter climates will also allow things to get to a melting temperature easier. Steep hills will cause the engine to work harder and create hotter exhaust as well.

To be on the safe side a turn down for the exhaust would be a good idea. I attached a link to a page that has all of the ones we carry.

The # 63153 has a distance of 12-3/4 inches from the center of the hitch pin hole to the rail of the carrier. For a carrier with a greater distance check out the Curt part # C18151 which measures 19 inches and also has a 2 inch rise.
