Seatbelt Retention Buckles

Ever had your seat belt buckles slap the side of your vehicle?  This can happen when the windows are down, top is down, doors are removed, rear seats are down or any combination of those situations.

These seatbelt retention buckles are easy to install and keep the buckle from moving.  Leaves you with a clean look and potentially less noise.

Comes with pre-mounted authentic 3M.

NOTE:  2 Door vehicles only come with a passenger side retention buckle for the front (1).  4 Door vehicles comes with passenger front and rear + driver's side rear buckle (3).

Why no retention buckle for the driver?

Put your seatbelt on while you drive.  You'll live longer!


Clean the application area and make sure it is free of dirt, dust, debris, Armor All, etc.

You may use an isopropyl alcohol wipe to prep the area as well.  Install in a very warm environment (70-80 degrees) and REFRAIN from use for 24 hours while the bond strengthens.

 After application, the bond strength will increase as the adhesive flows onto the surface (also referred to as “wet out”). At room temperature approximately 50% of ultimate bond strength will be achieved after 20 minutes, 90% after 24 hours and 100% after 72 hours. This flow is faster at higher temperatures and slower at lower temperatures. Ultimate bond strength can be achieved more quickly (and in some cases bond strength can be increased) by exposure of the bond to elevated temperatures for 1 hour).

Great in theory

So I like the concept around these. However, there are a couple issues that have occurred since installing. The biggest one is that there is still a lot of movement coming from the belts. I think if these were constructed a bit taller and longer, not thicker, they would securely hold more of the belt. Next, if your passengers do not know they are there, then they pull and the whole thing comes off. Right now I am looking for more 3M double sided tape to put on one to give it another go. Sadly not a fan considering the money spent.

Good idea, just don’t stick.

The adhesive needs to be a bit stronger.

I actually installed this on my Tesla Model Y. As the seat belt has an annoying rattle and it work’s perfectly.

Great simple concept

Love this and has made a significant difference with the seatbelt blowing around when the top is off

Straightforward Solution

The retention buckles work as advertised. Very simple install and they are holding up well. I did install them with a slight angle (not parallel to the ground) so I could match the natural angle the seatbelt sits. Works great....(hopefully) lasts long time!

Tape Didn't Hold

It was a great idea, and I will try to re-tape them back on. However, they did not stand up to the force of three teenage boys growing muscles. All three buckles in a single day were grabbed and ripped from the plastic walls of my Bronco, never to maintain the stickiness again. :(
