Precision Engineered for Hyundai i40: The Ultimate Power Liftgate Solution.
The Hyundai i40 (especially the Tourer/Wagon model) is known for its spacious cargo area, but the factory electric tailgate struts (OE: 81780-3Z100) often struggle after years of use or when the rear hatch is modified with extra insulation, cameras, or bike racks.
As a specialist with 20 years in intelligent door systems, we offer more than just a replacement. Our Custom Auto Tailgate Assist is designed for the high-frequency demands of repair shops and modification experts. We provide reinforced motor torque and customizable lift force to ensure your customer's i40 opens smoothly and stays open safely, even in extreme weather or with added weight.

FAQ
Q1: Is this electric strut a 100% direct replacement for Hyundai i40 OE 81780-3Z100?A: Yes. Our struts are engineered to be 100% Plug-and-Play. They match the exact dimensions, connector types, and communication protocols of the original Hyundai i40 (2011-2019) system. Your technicians won't need to flash the ECU or cut any wires, significantly reducing labor hours in your shop.
Q2: We have a client with a modified i40 Wagon (heavy rear load). Can you customize the lift force?A: This is our specialty. Unlike standard aftermarket parts, we can calibrate the internal pressure (Newton force) and motor torque of the 81780-3Z100 unit. If your client has added soundproofing or a rear carrier, we can provide a "Heavy-Duty" version that prevents the common "half-way drop" issue.
Q3: What is the sample policy for repair shops and wholesalers?A: We understand the need for quality testing. You can order a single pair as a sample. To support our B2B partners, we offer a Price Difference Credit: if you later place a bulk order (MOQ 5 pairs+), we will refund the difference between the sample price and the wholesale price directly to your account.
Q4: How do these custom struts perform in extreme climates (e.g., Northern Europe or Middle East)?A: Our Hyundai i40 actuators feature IP67-rated sealing and high-grade synthetic lubricants. They are tested to operate flawlessly from -40°C to +80°C. This ensures zero "stiffening" in winter and no "fluid leak" in summer, which are the leading causes of failure in cheap generic struts.
Q5: What is your warranty and claim process for B2B distributors?A: We provide a 1-year comprehensive warranty. If a unit fails due to manufacturing defects, we don't just "repair" it—we ship a new replacement ASAP with your next order. Each strut undergoes a 30,000-cycle stress test before leaving our Chinese factory to ensure your shop's reputation stays intact.
Q6: Can we order these for other Hyundai models under our own brand (OEM)?A: Absolutely. With 20 years of manufacturing experience, we offer full OEM/ODM services. We can laser-etch your brand logo on the strut casing and customize the packaging for your local market, provided you meet our ODM volume requirements.
