Very beefy- 2-3x beefier then the stock sliders. 5 starts for sure, from a design standpoint I wish the step was slightly smaller (skinnier) and tapered more from the edges in.
Install was easy enough, but expect 2-3 hours if you use your bronco offroad, lots of time spent cleaning some of the bolt holes that were not being used previously. I recommend using a very very small crescent wrench instead of a 16mm wrench- you'll understand when you get to that part.
They also seemed to have added weep holes which is perfect as I was planning on drilling some.
100% trust putting the full vehicle weight on these things.
The packaging was too good
