Description
If you're finding water inside the cab of your '10-'27 Ram truck, it can be a deteriorated third brake light gasket letting water in. This gasket will not shrink or take a set like the cheap factory PVC foam gasket. This automotive spec foam rubber gasket is .187" thick and has an adhesive backing to attach the light.NOTE: It is not a fun job, but it is necessary for the old gasket be removed and cleaned off the third brake light for a good seal.
This third brake light gasket is designed for use with those trucks WITH a brake light camera.
This will also fit 2019 to 2024 Ram 1500 classic and the 2011 to 2027 Ram 3500/4500/5500 cab & chassis models.

I might have just gotten lucky, or maybe the temperature was just right on the day I tackled this project, but removal of the old gasket wasn't that bad. I used a plastic caulk removal tool to follow as I slowly pulled up on the old gasket to try and keep as much as possible of the old adhesive on the original gasket. Some Acrysol and a microfiber towel pretty easily removed any remaining adhesive residue and dirt. Within 20 minutes I had the light removed and the mating surface completely clean down to the plastic.
We'll see how long this new gasket will last (I had to give a rating to get this note submitted), but it is definitely not the spongy OEM stuff that was completely compressed and ineffective. But, I wanted to give some feedback on the process for removing the old gasket.

It was easier than expected. I used a hair dryer to warm up the old gasket and adhesive in small sections. Most of the adhesive came off with the gasket, and the remaining bits were easy to roll up with your thumb as you went along. A follow up with a cloth dampened with rubbing alcohol completed the job.

Appears to be quality product. Removal of the old gasket was straightforward. I did not have any issues with the old adhesive. Following the directions of misting , some windex onto the new gasket definitely made installation easier. I tested with some water after installation appears to have resolved the leak only time will tell as It's been installed for 24 hours, at the time of writing. I will amend review if anything changes.
