mine came with it also, (bought one that the dealer had ordered for someone else then reordered w/o the beadlocks so it would get built sooner than later) but i as well am surprised by how strong/nice it is thus far. i have yet to haul very heavy, like construction loads with it in use yet, just some totes/ light tools/ etc. it is nice though for the easy in / out with the box link, wish it would lock though ( have been worried about it 'going missing' while parked in some not so nice home depot lots from time to time, if people know how easy the box link works).
it's the perfect width for me to throw gas cans in between the front of the bed and divider when installed in the front position as well.
If you could find one for 200 or so i'd say its worth it
