Normally, if you request a 4S dealership to install a genuine bumper, they are typically required to use OEM parts. Here are the relevant details: Classification of bumpers: Bumpers available in the market are generally categorized into OEM and aftermarket types. OEM bumpers are supplied directly by the original manufacturer, while aftermarket bumpers are mostly produced by secondary manufacturers or even small workshops. Advantages of OEM bumpers: The advantages of OEM bumpers lie in their toughness—they are highly resistant to deformation even under intense pressure. Additionally, being supplied directly by the manufacturer ensures better quality assurance. Although they may be more expensive, bumpers are crucial safety components, making the extra cost worthwhile.

I'm a veteran driver with 20 years of experience and have replaced bumpers two or three times. The ones from 4S shops are usually genuine parts because they source directly from the automaker, with packaging that includes codes and brand logos to ensure quality compliance. When my car was rear-ended, the new bumper I got from the 4S shop fit perfectly, matched the color exactly, and gave me peace of mind while driving. However, sometimes 4S shops might use aftermarket parts to cut costs, so you should always confirm the part's origin before paying—check if the invoice states 'genuine part.' Genuine bumpers offer advantages like harder materials, better crash resistance, stricter safety testing, and typically come with a manufacturer warranty of about two years. Aftermarket parts are cheaper but may rust or deform. My advice, especially for new car owners, is to insist on genuine parts at 4S shops—safety first. After replacement, have the technician perform an alignment check for added assurance.

I'm particularly fascinated by car parts and know that the bumpers at 4S shops are highly likely to be genuine OEM products, as they have direct agreements with the automakers, and their parts inventory is fully customized by model. The advantage of OEM bumpers is traceable batch numbers, precise hole alignment during installation without affecting radar or sensors, avoiding risks like looseness or collision issues common with aftermarket parts. In terms of quality, OEM parts use high-strength plastic or metal, undergo rigorous testing before market release, ensuring driving safety. Non-OEM parts may be 30% cheaper, but they often feature thinner materials, noticeable color discrepancies, and may require rework. When I replaced my car's bumper at a 4S shop, I made sure the order list specified 'OEM' for transparency in pricing. I recommend car owners balance their budget but prioritize OEM parts to extend vehicle lifespan and maintain resale value. Post-repair dynamic balance testing is also advisable for reliability.

Safety should always be a priority when using vehicles. Our family only trusts original parts from 4S stores for bumper replacements. These parts are genuine items sourced directly from manufacturers, with standardized packaging and clear coding, ensuring perfect fit with the car's structure and color. Original materials are more durable, reducing accident risks. Aftermarket parts may be cheaper, but they often use inferior materials, loosen quickly, and pose significant hazards. When purchasing at a 4S store, check if the invoice specifies 'original parts' to avoid future troubles. I once replaced my child's car bumper there—the staff unboxed it on the spot to confirm authenticity, offering a two-year warranty. The money was well spent. While there are ways to save costs, safety comes first; choosing original parts is the right decision. After replacement, always check for stability.
