I installed the Shrockworks dimpled sliders and they were a complete pain in the ass.
2016 TRD PRO here.
Took me close to 3 hours or so for both sides.
I did have to drill 3x. Once on the front passenger side and twice on the driver's front.
Also, the stick nuts were the most time consuming part trying to get it lined up the with bolt in the frame. There are these plastic covers you pop off on the frame and then you have to wiggle/bend the nuts into the frame and behind the hole to line up the bolts.
If I had to do it over again I'd take the sliders to a shop to have them welded on stead of trying to use the bolts and nuts.
Other than my install gripe, they are very well built and are 45lbs a piece.
