They fir and work exactly as expected. If you're doing a self-install you need to carefully read the instructions and take the time to watch some YouTube videos and be sure you know what you are doing before you start. Getting the brackets mounted isn't too difficult but you have to take the plastic fender liners (if you have them) off first. If your year/model truck requires you use the wire tool to pull the bolt and spacer into place in the frame just take your time and think it through. They work great and make things surprisingly easy. The difficulty is multiplied when you go to install the rails in the bed. Measuring, marking, and drilling the holes in the bed floor is easy but getting things bolted together and tightened up isn;t easy at all. Patience and diligence is necessary!

Very nice sturdy brackets. My 2016 Silverado already had the threaded nutserts in the frame. I was able to install, bolt down, and torque these brackets without removing the rear wheels, but you need to install the rails and bolts down through the brackets before you put the final torque on the brackets. Put the brackets on and hand tighten the bolts then do the rails, then do the final torque on the brackets. Be aware that these brackets are one for the left side and one for the right side and you can't switch them. If you look at the bolt holes in the top of the brackets the rear most holes are more to the center of the truck. This is because the rear rails are bolted one notch more inward than the front rail. It sounds complicated but when you look at the instructions and get the hardware in front of you it makes sense. One other thing. If you got the Duramax, on Youtube they show them cutting the heat shield. You don't need to do that if you use a flex box ratcheting head wrench and undo the four 13 mm bolts holding it on. The clearance is tight but with that tool you can get the 4 of them off about 5 minutes each. Don't cut the heat shield if you don't need to.

These worked great on my 2016 2500HD SLT Duramax Diesel. The instructions are not clear. It took my father and I a while because we had no truck lift and I didn't watch the video before we started. I highly recommend watching a video. It made sense after that. I took the spare tire off, Bent the heat shield out of the way (bent it back when done) on the passengers side. On driver side we had to remove the cover inside the wheel well to access the bolts due to the fuel tank on that side. The layout of rail and drilling was very simple. Everything lined up perfectly. The most difficult part of this entire process was getting the washers and nuts on bolts and getting them tight due to space. The space is very very small to work in especially because we didn't have a truck lift. Also I ran the bracket bolts in from the outside with the pre drilled holes but we also fished the bolts through the inside. Not sure you need 4 bolts on each bracket to secure it to the the frame but we did it anyway. some guys only put the two outside bolts in. Use the wires provided and it is not a problem. You can't do it without the wire. We tried forever before we figured out we needed the wire. Again youtube video before you start. This job over all took us about 6 hours. Had we watched the video first we could have knocked off 2-3 hours easy. Brent

First ordered got returned before I ever got it because of poor packaging one I got the order it only had one bolt fish wire with it when there should be two so you can hold both bolts in place it was a total pain to get the bolts thru the frame.

Product is very heavy duty and all holes lined up perfect!! I would recommend using a ratchet wrench and a lot of patience if installing without help!! Nothing to do with product, just the rail bolts are difficult to get to!!

It fits good, looks good, and works well, not easy to install at all, holes line up with tops of frame rails and made it a challenge to get the bolts in and nuts tight. but one it was in it looks great, painted the bolts black and can not even tell its there unless your looking for it.

2011 chevy Silverado 2500hd. It worked, but not like I hoped. The bolt holes are tapered inward 1†on the rear bolts, and the front left was a pain in the butt to put on because there was no access to it. Had to remove the tire, shock, and lower the fuel tank (upgraded fuel tank size). Definitely well built and comes with everything needed to do it, but definitely won’t do it myself again lol

Looked to be very heavy duty and quality brackets. Holes matched the frame of my 2013 Chevy Silverado LTZ HD Duramax Diesel 3500 perfectly. The supplied hardware and instructions were very good also. It was a bit of a job to install as the work space between the truck frame and the box is tight and hard to reach especially above the diesel tank. I found it to be a 2 man job, one in box and me under the truck. You will need larger wrenches, socket set, and power drill that many may not have. And a torque wench, although a few of the bolts were not able to get torque wrench on them. So if you are not mechanically inclined and don't have the bigger wrenches, best to leave the install to someone who is.

So much better than a universal installation kit. Bolts up to existing factory holes and threaded inserts in the frame. Drilled my holes per the simple included instructions and it went together perfectly.

Product arrived with a hole torn in the box and the hardware kit missing. Emailed vendor and hardware kit was supposed to be sent asap. A week later still nothing, emailed again and new package arrived next day. New package was also torn, however hardware package was still inside this time but bag was torn and hardware was loose inside box. 2 days later the promised hardware kit arrived. Got what I needed and worked well just took longer than expected.

Fit good. Instalation was about what I expected. There was a review getting the brackets mixed up, but they only go on one way. Put on a 2016 GMC serria 3500.
