Snoop's Take

The ESI Ultimate Tailgate Seal is a patented product designed to fit 2020 and newer Silverado and Sierra 1500 trucks, effectively sealing the gaps around the tailgate to keep out dust and water. Made of automotive-grade EPDM rubber and featuring 3M ST1200 tape, this product aims to enhance the usability of your truck bed by preventing unwanted debris from entering, particularly useful when using a truck bed cap or tonneau cover. Consumer feedback highlights its effectiveness, with many users confirming that it successfully keeps dust and dirt out of their truck beds, with one stating, "Can confirm this. Have them on mine truck and work great." However, there are some concerns regarding the adhesive not holding well over time, as noted by a user who mentioned, "80% of it fell off within a month." Additionally, some users have reported the seal making the tailgate more difficult to close, indicating potential design flaws for other truck brands. Overall, while the ESI Ultimate Tailgate Seal has received positive reviews for its sealing capabilities, the mixed feedback regarding adhesive longevity and compatibility suggests that potential buyers should consider these aspects before purchasing. It may be recommended for those specifically looking to improve dust and water resistance in their Silverado or Sierra 1500, but caution is advised regarding installation and long-term performance.

Core Power Plays

The specs and strengths that make it shine.
Discussion on sealing effectiveness in various conditions
I don't want to be fighting a losing battle to keep my bed and anything stored in the back from getting damp!
the low pressure at the rear of the rear kinda sucks a bit of dust/ snow in around the tail gate.
the area near the clamps was wet and the side of my bedding on that side was moist.

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.
Discussion on alternative solutions to sealing gaps
There is a kit from a company called ESI and another called Ramseal that are designed to close this gap.
So its weather striping....and its patent pending lol.
Marine hatch tape. It’s used ti deal boat hatches from water intrusion and it will smash down like a gasket.
Use this dude.
Experience with alternative sealing methods
No issues so far.
Way better than the soft topper at keeping dust out, but it still gets in.

Would like to do something like that for my 2024 but not sure where to start.
Probably going to try the ESI also.

Users seeking various sealing options
What are some options for sealing that area a little better?
Depends how big of a gap it is.
I think this would be best and the most versatile.
