Simply put, excellent bumpers for the senton 3s models. My sons and I beat the crap out of our trucks, and these bumpers take it all.
My suggestions to the people that have issues with screw stripping, and for install issues.
1.) Try to take your time, use thread locker (even though it's plastic), and just install in reverse of how you removed the stock bumpers.
2.) My 14-year-old son had ours mounted on all 3 trucks in 45 minutes (fronts and rears on each truck).
3.) It's a simple process for installing, just start with parts closest to the truck body, and mount the bumper bars to the bumper plate BEFORE mounting to the truck.
4.) Thread locker even though your mounting to plastic is a huge plus. It helps take up slack/space after you burr the holes from uninstalling your old oem/custom bumpers.
