Bak Revolver X4 Shims

[swalters]

I purchased a Bak Revolver X4 tonneau cover. One side of the rails blocked my tailgate from closing. It was only off by maybe an 1/8”. Tailgate worked until I rolled the cover closed. After several attempts and calls to customer service, they recommend I use shims and they sent me a set. Any recommendations on how and where to place them?  Thanks!

Try this method of installing your cover. It worked great for me.

It works perfectly with the power tailgate. Here is my step by step for putting mine on. The directions that come with it make it more difficult than it needs to be and there are a couple things that need modified from their directions.

 

1. Open the box and unpack everything. Keep the box until you register the cover with BAK for the warranty. It has all the labels with the serial numbers on it.
2. There are 2 weather-strips rolled up, a 3/4" and a 1/4". The directions say to use the 3/4" all the way across the headwall but when I went to tighten the cover down the 3/4" was way too tall for the cover at the headwall.  Clean any dirt off the headwall with alcohol or wax & grease remover. Now put about 3" of the 3/4" at each end of the headwall starting from the plastic cap inward. Keep the weather-strip on the farthest rearward flat part of the headwall.
3. Install the 2 rails on each side of the bed like the instructions say, push them up against the headwall and clamp them in. Now use a razor knife and cut off the 3/4" weather-strip that is not under the rail.
4. Now take the 1/4" weather-strip and put it on the headwall between the 2 rails. Keep the weather-strip on the farthest rearward flat part of the headwall.
5. Now take the bedcover and roll it out on the rails and remove all the packing on it. Take the end of the cover an put the 4 bolts in the slots and put the end of the cover in place so the bolts go through the brackets at the end of the rail. Now put the washers and nuts on the bolts, just hand tight, they will get the final tighten later.
6. With the bed cover all the way flat and the tailgate down, stand in front of the tailgate, lock the tailgate end of the cover down and pull the cover towards you. now close the tailgate softly by hand. You will see that this will push the bed cover towards the cab and put it in the right place for sealing against the tailgate.
7. Lower the tailgate, get your tools and crawl in under the bed cover to the headwall without moving its position and tighten the 4 nuts that hold the headwall end of the bedcover to the rail brackets.
8. Now crawl out of the bed and test everything. It should all work and seal up nicely.
