Very easy installation! Although I installed it without help, it would have been much quicker and easier with two people. After installation I am very satisfied!

I'm installing the X4 on a 2019 Sierra short box. Shipping was very fast and the unit arrived in good shape. My installation was required twice as shims were not included with the shipment. Check other reviews and you will find that the width of the bed is about 1/4 inch wider on a GMC than Chevy; without shims, the cover will not line up with the track. I called BAK and talked to support, they requested I send an email with what I needed and they would ship. They shipped out the foam shims (not what I had requested) and they arrived quickly. I ended up finding my own metal shims to use. Also, one of the plastic clips to hold the cover when rolled up broke with very little pressure - I requested replacements of those as well but they have yet to send. Overall, I like the cover and the quality and design seems very good. Support from BAK is hit or miss; I'm hoping that they send new clips as I tried to order some and it's going to be impossible to find something on the web that well work.

Love this product on my 2017 Silverado 2500HD Crew Cab and would give it 5 stars if not for slight damage on one of the rails I suspect occurred during shipping. I was able to tap out a small dent in left bed rail and use with no issues. I also have a very small 1/4” gap at one corner of the tailgate that I expect will be an easy fix when I have time to readjust the rail on that side. Cover is made Very solid and I have no doubt will keep my bed very secure and dry for years to come. It also looks very nice. It took me ~1hr to install because I took my time, but if I ever install a 2nd, could do in 20 mins. This product was worth the higher price tag in my view.

Installation video on website was very helpful. As a result installation was straight forward. Cover looks so clean on my new F-150. Love the low-profile appearance. Rolling up the cover is incredibly easy. Very pleased.

The X4 Top is one fine looking cover. See photo attached. The only thing that was really frustrating was the install. If they would have provided me with the dimensions for rail distances in the front and back of the bed I could have properly shimmed the rails before I installed the cover between the rails. What should have been a 2 hour job turned into an 8 hour job since I needed to install the rails and top 3 times (with one trip to Lowes to buy some additional shims) to get the proper distances. If they don't provide these distances in the future I would lay the cover out on the lawn and measure the distance between the outside of the black plastic underside pieces (these pieces lay in the rail tracks on both sides) on the front of the top and the back and then make sure the rails matched these distances (actually the rail spacing should be 1/8" to 1/4" wider). Top is great looking and function, now just hoping that it weathers well.

This is my second Bak revolver tonneau cover. I had the X2 on my previous truck (standard bed) and it performed and operated exceptionally well. The X4 on my new truck (short bed) doesn't operate as well as the previous version. The bed rail looks like it was roughly cut at the factory at the tailgate end which is a very sharp unfinished edge. It's as if it was built for a standard bed and cut to fit a short bed truck. Although the cover is aligned and lays in the rail as designed when rolling the cover open to expose the bed of the truck the cover doesn't roll as tightly and tends to slide or scoot on the rail. The rail alignment and installation has been checked and re-checked to insure proper fit.

This was my second BAK cover. In both cases I was very pleased with the fit and finish. You get what you pay for, so goes the saying... you pay more for BAK but it is worth it in the long run. I considered less expensive brands but wisdom and experience led me otherwise.
