It's the Prospeed rack. You do need the short rails to install the rack but I love this rack for the lack of noise it generates and the way it looks. I had the Frontrunner rack before this and do think the FR rack is a bit more functional especially since I had a lot of their accessories. However, the FR rack is also very loud to me even with their wind screen installed and since the LR is also my daily driver, the noise issue bothered me plenty.
