Give yourself some slack - with the Seat Belt Adjuster!

This easy-to-use seat belt adjuster allows you to control the tension of your seat belt and can be adjusted to fit any individual. This useful device moves the seat belt off of your neck to end irritation, chafing and discomfort. It can even prevent clothing from wrinkling under the seat belt.

The Seat Belt Tension Adjuster works by attaching to the top of your seat belt by creating slack without compromising safety.

The Seat Belt Tension Adjuster comes in packs of two so you'll have one for the driver and passenger or an extra for a second vehicle.


View a video on how to install the Seat Belt Tension Adjuster below in the video section of this page.

After buckling your seat belt:

1. Separate the top of the adjuster from the bottom by holding both pieces and sliding them in opposite directions.
2. Position the Seat Belt Tension Adjuster on your seat belt strap where it retracts, with the red lock and flap facing you. Snap the top and bottom back together with the seat belt in between.
3. Slide adjuster towards the seat belt retractor, and pull the strap not more than one inch out, allowing only enough slack for your comfort.
4. Lock into position by sliding the red tab to the right. Unlock by sliding the red tab to the left or to re-adjust.

    Not what I expected

    Posted by Kim Hensley on 4th Jun 2021

    I don't think these are very user friendly. You have to loosen it each time you take the belt off or put it on and with all the constant sliding, mine came apart and the red lever fell out. They are good when they are in position but too much fooling with each time for me.

    These are great . A friend of mine had shoulder surgery and I gave him a pack. These were great in taking the pressure off of his shoulder.

    I have been using this style of extender for years. Makes driving so much more comfortable. Easy to use and install.
