The Diamond League gala in the Moroccan capital will be the discus duo's second of the season.
In Birmingham on 21 May, Daniel Ståhl was third in 65.97, while Simon Pettersson was last in a modest 56.82.
Since then, both have thrown best of the year, in Icelandic Selfoss Ståhl reached 69.27 and Pettersson 65.94.
The long jumper Thobias Montler, who took silver at the indoor WC this year, will also compete in Rabat.
And he gets there with top results in the back - in Greek Kallithea he touched his personal best outdoors, 8.38.
In addition, Andreas Kramer runs 800 meters, and Maja Nilsson jumps high jump.
You can watch the gala live on SVT Play from 19.15 and also on SVT1 from 20.00-22.00 - or in the player above.
