BAK Revolver X4 Bed Cover - 2019 Sierra SLT/AT4/Denali Short Bed (Beware of Fitment Issues)

[Jaketab]

Just received my BAKFlip MX4 order below for a 2020 GMC Sierra Denali 1500 series – short bed.  (With multi pro tailgate)

Two concerns before I completely remove the parts from the box. 

The inside width measurements of the truck bed vary.  The front width at the rear window measures 63-5/8”.

The rear width at the tailgate measures 62-1/8”.

The hard tri-fold panels measure 62”.  Meaning front panel is 3/4’' will be too short on each side.

This may be too much overlap to fit ??? 

I've already sent an email to REALTRUCK and will contact them by phone tomorrow.

 

The second concern is the bed liner is the factory stock spray on liner.  The front sealing bulkhead strip most likely not stay adhered to the textured finish.

I just got the x4 for my 2021 Sierra AT4....Width wise it seems to be ok as far as I can see....but front to back is the issue. the tailgate doesnt even hit the rubber seal when shut....but I can't pull the cover any closer to the tailgate as the plastic pieces where the cord release is hits the metal of the rails and wont shut....I'm going to call them Monday and see what can be done, because as this is it will leak like a sieve.

 

I had the x2 on my 15 sierra and it fit much better and didnt leak at all. The tailgate pressed into that rubber seal really well.

 

Danny,

Have you measured the width of your bed at both the front and rear ?

If so, what are the measurements.?

I just received the BAKFlip MX4.   The hard aluminum panels measure 62".

The width of my 2020 Sierra Denali varies from 63-5/8" in front to 62-1/8" at the tailgate.

I have the 2020 Sierra, with factory spray liner, with multi pro, the mx4 fits fine. The weather strip has stayed in place for the past 4 or so months.

What was BAL's solution to your problem with the cover? I also have an 2021 AT4 and was looking at purchasing this cover..Please advise.
