Bakflip MX4, OEM cargo divider and bed mat install

I’ve recently acquired an OEM cargo divider, 4 bed cleats and an extra block heater cord all for $150 CDN on Kijjiji which I consider a smoking deal!

Anyway, today I had my Bakflip MX4 installed and picked up an OEM bed mat..man is this thing grippy! As you can see I also had to drill holes in the bed mat for both Bakflip drain tubes, no biggie.

As we all know, the Bakflip tonneau cover drops the bed rail tracks an inch or so and the Bakflip bracket design also pushes both tracks about 3/4” closer than they were.

To install the OEM cargo divider, you simply flip both brackets upside down (so that the cover doesn’t hit the knobs of the divider) and trim ~3/8” of an inch off each side of the cargo divider top rail.

After doing this, the divider now fits between the rails just fine, but the thickness of the bed mat takes up any clearance you had at the bottom of the divider. To get around this, I’ve read about people using spacers, but I went a different route.

Using an angle grinder and a zipcut disc, I trimmed about an inch off the bottom the whole way across. I just trimmed along the indent on the bottom rail, using it as a guide. Seems to work fine and I have about the same amount of clearance on the bottom that I would have had without the bed mat.

 

I’ve been looking at getting an MX4 and was wondering about dropping the bed rails. Are there instructions from BALflip for doing this that comes with the cover? Or is this just a little known fact among the forum? If so, can you share?

Also, any leaking issues? The last cover I had on my 15’ leaked live a sive... trying to avoid that on my 19’.

 

I didn’t do the install, but the BakFlip comes with brackets that attach to the factory threaded holes for the bed rails. The factory rails attach to the bracket. Looks pretty straightforward to me.

It leaks a little, but consensus on the forum here is that every bed cover leaks to some extent. I get a little bit of water in there when I run it through the car wash, but not much.

I don’t get why some people complain about a bit of water getting in..what are people carrying around their truck boxes that’s so delicate? mortgage documents, wills, antique manuscripts, grandma’s ashes etc?

 

Are you still able to have the bed cleats (tie downs) on with this cover when it’s down or it hits?

 

Yezzir. The rail is low enough that it doesn’t interfere at all with the operation of the bed cleats.

I took those stupid drain tubes off as well. You can’t push stuff to the back of the box all the way without squishing them. Useless
