Might be. I also considered the Mopar box, which is 71" long, and it appeared that it might JUST reach the oem antenna without bending it - - or perhaps bend it a little. But I wanted as much box length as I could have (skis!), so after determining that the Atlantis (74" long) was as large as I could go without interfering with an open tailgate, I installed the sharkfin.
Thule was very helpful in providing information; particularly helpful was the distance from the rearmost position of attachment to the actual back of the box.
The sharkfin went on easy - - and I installed it in freezing weather using a hair dryer to warm up the surface. I detect no audible difference in reception, and it looks great!
