2021 w/ sportsbar off a 2018, lo pro tonneau cover and multigate

[Juddmann]

I upgraded from a 2018 AT-X to a 2021 X31 SLT. I pulled the sportsbar and wire harness and managed to fit it on the '21.  The lo pro cover worked and was identical to the gm cover offered for the '18. The gm cover for the '21 covers the stake bed pockets so the bars wouldnt work. I had modify the install instructions and very minimal modifications to the cover and none to the truck itself. Compared to the cover from the '18 to the '21 thr only differencenin look is the tail of the cover. With the multigate it sits higher than what i was used to but it still looks good and functions 100%. Its been on for a day so I'll post how it holds up over the winter

*pics of both '18 and '21 covers coming soon*

Here's a pic of the '18 AT-X with the original sports bar and the factory offered tonneau cover gm p# 19355363. Which went on exactly the same way as the lo pro for the 2021. I ordered the cover for a '21 which doesnt give you the option for with or with out sports bar so i had to mod it a bit to fit. Had i ordered a '16-'20 i believe it would be the same cover just with the option for the sportsbar. The only difference between with or without the sportsbar is a second gasket strip that goes along the bed side between the rails. Instead i bought 1" wide 1/8" thick aluminum strips as a filler and a bead of silicone along the bed rail. So far some minor drips but hasnt been through a car wash yet.

This is the 2nd strip of gasket/ double-sided tape from the gm kit. The sports bar hangs on the side of the bed rails so they need to fill the gap they create when the rails are clamped on. The double cab cover came with 4 clamps on each side and had very minor leaks and held up in car washes.
