Ease of Installation
Ordered these sidebars and had them within 5 days of ordering, excellent delivery timeline. Easy install, took about 25 minutes on each side start to finish. (I was working alone and a bit of a perfectionist - checked every bracket for perpedicularity to the frame after assembly - no problems!) Instructions were straightforward but I would have liked to have a torque rating for everything - dislike having bolts work loose from under tightening as much as I dislike stripped threads from over tightening. Just went conservative and have checked them twice in the first 4,000 miles - no problems. The polished bars and the welded end caps are great. Have seen too many rusted out front caps or missing plastic caps so highly recommend this design. I would have liked sturdier mounting brackets but they do the job and I went with everything stainless as I plan to have the truck for 15-20 years.
