It is specifically engineered for the 2019–2020 Elantra​ body style. While parts are often cross-compatible, you must verify your exact model year and manufacturing location (check VIN) against the seller's full compatibility chart. 2. Brand Features DIY Video Support:​ provides a large library of "View Before You Do" installation videos. Check their YouTube channel or the product page for a step-by-step guide to replacing the fender liners. Direct Fit Design:​ Components are pre-assembled and designed to match the original equipment, aiming to eliminate the need for drilling or trimming. Quality Assurance:​ The brand emphasizes over 25 years of experience in manufacturing replacement parts, with fitment often verifiable through Amazon Garage or other vehicle selectors. 3. Installation & Pre-Purchase Checklist Tool Requirements:​ Basic socket set, trim removal tools, and a jack/stands if you need to remove the front wheels for better access. VIN Verification:​ For absolute certainty, cross-reference the OEM numbers above with your Vehicle Identification Number (VIN)​ using a dealership parts catalog or online database. This is the most reliable way to confirm fitment beyond just the model year. Inspect Mounting Points:​ Before installation, check the fender well area for rust or damage to the mounting tabs, as this can affect the secure fit of the new liner.
