Poor engineering but woks
When in the first step it tells you to pull everything apart and wire everything up to see if it functions make sure you do that. The motors were wired possibly backwards or on the wrong side of the lowering arms swapping things around I made it work but it's still not perfect. now the motors are on the front side of the lowering arm but it to goes in the correct direction. passenger side rear door and the driver side rear door sensors had to be swapped. they were labeled wrong.
Putco Boss 4" Round Nerf Bars
The negatives: When mounting the bars, I had to run the threads in the rivet nuts of the bars so that the bolts would start. To prevent rust, the bolts should have been stainless and the brackets powder coated. The front step pad is too far forward making it more awkward to enter and causing your foot to scuff the polished bar. Too expensive for the above mentioned reasons. The positives: They're relatively easy to install, look good and attractively cover the full length wheel to wheel.
