The higher side of the weatherstrip goes toward the outside, correct? | | | | | Joined: Jul 2003 Posts: 586 Shop Shark | | Shop Shark Joined: Jul 2003 Posts: 586 | I asked a similar question on the GMC forum and here is the answer I got: The taller rib should be laying against the body of the door and the short rib should make contact with the truck body when the door is closed. The square side is against the door and the valley goes toward the truck when the door is closed.

See This ... scroll down to the last picture ... I think you can see what I mean there.

rib should be on the outside. At least this is
what a couple of other people have told me.

Many people buy a kit from Chevy Duty (good price - good quality). The two kits that I bought had a copy of a copy of a copy of a drawing of the weatherstrip in the opposite orientation than that shown in the Factory Assembly Manual.
I installed the weatherstrip as described by Alan (and the Factory Assembly Manual) and had no problems.

I don't remember where I originally got my info from about that ... but I do know I research things well before I go ahead; I was sure that was the correct way when I did it; and everything works great, so I'm 99.9% sure this is the way.
Also, since the idea is to create some compression between the rubber and the door-frame when the door is closed, it sure doesn't make sense to "hide" the crown by tucking it into the corner where it can not compress.

Did one door last night and the other tonight. Used horvath's high side out method with Chevy Duty weatherstrip. I put the adhesive on the door using a small disposable brush, the kind you use for solder flux, perfect width plus long enough to do the front around the hinges, plus they come two to a pack so one for each door. doors close about as easily as without the weatherstrip. thanks to all who posted. | | |
