I installed this on my 2021 4Runner with the adhesive provided and no drilling. It has been a few months and it’s still solid. I live in Hawaii and the temps in the car have reached over 100* F pretty consistently and the adhesive has held up very well. There are a lot of attachment points for whatever you want to use it for. I only wish they sold the magnetic mount that it comes with so everything can match up. I use it for my phone and baby monitor. I would purchase this again.

Love this ram mount kit

Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121, Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121

All i can say is wow. This is an amazing ram mount kit for my 22 Silverado custom. All the hardware is top notch. The metal is all powder coated black with a nice grey American flag. There are so places to be able to mount addition arms. The phone holder it comes with is solid aluminum with a nice tight spring. I rate this 10/10 and for the price you can not beat it or find another better. I didn’t use the adhesive on the bottom so i can’t speak on that but i can only imagine it is really good as well. Hands down is just as good as the super expensive bulletpoint mount you see advertised. Don’t hesitate to buy.

Looks great

Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121

Fits great and is heavy enough to stay put. I used the adhesive backing to install as I did not want to drill into my truck but it still works well and I have had no issues with it popping out or anything else.
