Can't buckle up in your Tesla Model 3? Seat Belt Extender Pros extensions are the highest quality extenders on the market designed to help you fasten your seat belt. Just pick your favorite color and style, and you are ready to drive safely and comfortably again.

No more tickets for not wearing a seat belt, and no fishing for seat belt receptacles between seats. With a quick click on each end, buckling up is easy again!

This extender is ideal for Tesla Model 3 drivers and passengers who can't otherwise buckle their seat belts, which may include some plus-sized people, police, fire fighters, sheriffs, and law enforcement officers with bulky utility belts, passengers in NEMT vehicles, people with mobility impairments and others.

When it comes to safety, quality matters more. Seat Belt Extender Pros offers the highest quality extenders on the market: the best value in the premium category of seat belt extensions. We don't just offer the safest affordable extenders to add extra car seat belt length. With the smooth finish metal surface, the sleek design and all available color choices, your extender will also blend in elegantly with your vehicle's interior.

Your safety is our top priority with no compromise. Unlike most belt extensions on the market, Seat Belt Extender Pros extenders are:

  • E4 or E8 Certified
  • manufactured in a US DOT-registered factory that is
  • in compliance with ISO/TS 16949:2009 for Manufacturing of Seat Belt Assembly and Components

Extenders are diverse and never universal. Did you know that seat belts are different throughout most Tesla models? Your belt's metal tongue and receptacle shape depend on the seat itself and the manufacturing year of your Tesla. Seat Belt Extender Pros has the expertise to make your search easy.

Our regular extender style is made out of woven seat belt webbing material just like the seat belts in your car. Rigid extenders stand upright.

    Model 3 seat belt extender

    Posted by Stan on 14th Apr 2019

    Id give this product a 3.8 star out of 5. The extender works and thats good but the quality of the belt connector is cheap. When you try to connect your original seat belt buckle , you have to force it in quickly or it wont lock in. I bought it for my kid to do it herself but I'm finding im still having to help her as it will disconnect if not clicked in correctly. Not sure if id buy again as I might as well use the original buckle.

    Just what I needed

    Posted by Sue Shayler on 23rd Feb 2019

    I had ordered the 5" extender for my car and then realized they were too long. Customer service was excellent and super responsive. They sent me the mini extender and it was exactly what I needed. No issues, no hassles. They even let me keep the wrong ones which I passed on to a grateful friend. This is great customer service. Will definitely recommend this company and it's products.

    Seat Belt Extenders

    Posted by Michael on 1st Feb 2019

    this is my second time to order extenders for my granddaughters. They worked great! No issues with the girls buckling themselves. They were happy and grandpa was happy. When their mom and dad got their new Tesla Model 3, I very quickly ordered the extenders for their car. Again girls and parents happy. Seat Belt Extender Pros is THE place to order this product. Not only is the quality of the extenders superb but the online ordering was very easy. Shipment was correct and fast. The return policy is outstanding, but I did not need to return either of my orders. So...would I recommend this product AND this company...ABSOLUTELY! Five (5) Stars is really too little to give Seat Belt Extender Pros. Disclaimer: I am not related to anyone at this company and I am NOT a shareholder/owner. I am just a very happy customer!

    Tesla Model 3

    Posted by Daniel W Colestock PE on 24th Nov 2018

    The front seats of the Tesla Model 3 have a different seat belt buckle type than the second-row seats. The second row window seats and the middle seat all have the same seat belt buckle type, and all three second-row seat belt buckles are recessed into the back seat to keep them out of the way ... so a set of short, stiff extenders are very helpful accessories to make it easier for passengers to buckle up, particularly seniors. There are over 200 different seat belt buckle "types", Extender Pros will help you order the exact right buckle type, and their selection and quality is top-notch.

    Works but not a perfect fit

    Posted by William C. on 28th Sep 2018

    For those interested, this works as expected but the four is not perfect. Would attach a photo comparing oem bucket with the extender but don't have an option to. The OEM is slightly shorter than the extender so the fit is slightly looser than expected so double check lock after inserting.

    Seatbelt extenders

    Posted by DAVID GRIFFIN on 11th Sep 2018

    The seatbelt extenders work great with the Tesla Model 3. Having the extenders make it easier because the Tesla female end is slightly recessed into the seat. Great buy!
