Just picked up two sets of these.
PN#bull4001
They are the 'pop- up' style. Overall nice quality and price. Direct fit for the stake pockets. 30bucks a set.
Fitment and installation was easy as it gets. No drilling and they look pretty good. I like the fact that they sit flush when your not using them. Looks clean.
Rated at 1000lbs each and I just tested them out yesterday. It was only to tie down a Honda crf50

...but still. its somethin right. True test will be a full sized bike
