Backflip mx4 weather stripping

So I noticed today that the weather stripping between the panels looks to be shrinking, possibly from the cold or fluctuating temps.

Looked on their website and couldn’t seem to find the part and wondering if it can be sourced from somewhere and if it’s easily replaceable.

Edit:
Both of them are like this, same side. I tried using some pliers to slide it but there’s no play anywhere.

open to ideas!

2020 shortbed if that matters.

Thanks!!

 

I would call them. I have replaced the opening bar at the tailgate. Talked to them twice. Can't remember the name or number of the company. It looks like it shrunk due to environmental exposure. Regular dressing applications of 303 is what they told me to use. Does it leak.

 

I’ll give them a call Tuesday. I regularly put 303 on it. Maybe an application every 2-3 months. Last one in November. If it requires more frequent, yikes! But okay.

from all the research I’ve done, looks like that hinge seal is only available under warranty so we will see how the call goes.

 

Mine is a 2017 and I have noticed some workmanship issues in mine. I think that it probably just hurts the appearance. Not the function of the cover at all.
