Thank you in advance.** A: I am not sure of the dimension because I did not measure but it is pretty standard because i tried the extension in 3 different cars (Ford Mustang, Chevrolet Tahoe and Honda Accord) it was perfect - I think it is standard so no worries regarding size. **Q: Can this product be used on a Kia Sportage 2020?** A: I do not know as I did not try on Kia but I tried it on Ford Mustang, Chevrolet Tahoe and Honda Accord and it fits. The seat belt dimensions I believe are standard all over. ## Customer Reviews ### ⭐⭐⭐ 3.0 out of 5 stars Very short *by F***L on Reviewed in the United Arab Emirates on 18 January 2022* Very short and sadly couldn’t do much as I was planning to use it for a fashion show as a belt around the waist ### ⭐⭐ 2.0 out of 5 stars Does not work on all seats *by N***N on Reviewed in the United Arab Emirates on 15 March 2022* Did not fit for the back seats of the car, only for the front seats. This was meant to be used for the children car seats but I have to now re-sell this item. ### ⭐ 1.0 out of 5 stars Not compatible with my 2 cars *by M***L on Reviewed in the United Arab Emirates on 7 July 2022* The product is ok, however I could not use it as it was not fitting neither in my Suzuki Swift nor in my Chevrolet Impala. So, it is not very universal in the end. :( ## Frequently Bought Together - KASTWAVE Seat Belt Extender & Seat Belt Tensioner, Metal Tongue, Certified Motors Sleeve Buckle Connector Suitable for Most Cars, Relax Shoulder Neck Give You a Comfortable and Safe Experience - MAXDOOL 2 Pack Car Seat Belt Clips Alarm Stopper, Hidden Seat Belt Buckle Alarm Stopper, Suitable For Car Metal Seat Belt Silencers Of Most (Black) - Tesla Phone Mount, MagSafe Car Mount for Tesla Model 3 Model Y, Foldable Hidden Magnetic Phone Mount Fit for iPhone 14 13 12 Series and All Phone, Tesla Model 3 Accessories, Tesla Model Y Accessories --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/358578806-kastwaveseat-belt-extender-and-seat-belt-tensioner-metal-tongue-certified](https://www.desertcart.sn/products/358578806-kastwaveseat-belt-extender-and-seat-belt-tensioner-metal-tongue-certified) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-29*
