Sea Sucker has redesigned their crossbar system, something they like to call their Monkey Bars. Apparently Sea Sucker was approached by Quadratec in 2019 about how they’d like Sea Sucker crossbars to work on a Jeep top but the ridges on Jeep rooves were just too tight for the normal 6-inch mounts. Sea Sucker’s solution? They redesigned their vacuum mounts to an oval shape! And another great thing about these bars is that, being a suction mount, they aren’t permanent and can be removed and attached whenever necessary! But no matter what you are driving, these crossbars will work for you as they are universal, being fully compatible with anything from a Cummins to a Honda Civic!
