HOOD HINGE, ACTIVE, RIGHT HAND FOR TESLA MODEL 3(2021) 1643846-00-A
For the 2021 Tesla Model 3, the right-hand active hood hinge 1643846-00-A is more than just a mechanical connector—it’s a precision-engineered component that elevates how you interact with your vehicle’s hood. Designed to mirror the performance of its left-hand counterpart while fitting the right side perfectly, this hinge brings a blend of smart functionality and rugged durability that aligns with Tesla’s commitment to innovation.
Crafted from aircraft-grade aluminum alloy, this hinge strikes an impressive balance between strength and weight. It’s light enough to avoid adding unnecessary bulk to the hood assembly, yet robust enough to support the hood’s full weight (up to 20kg) through thousands of opening and closing cycles. The surface undergoes a specialized anodizing process, creating a matte silver finish that not only resists scratches and corrosion but also complements the Model 3’s sleek exterior lines.
What sets this hinge apart is its active damping system—a feature that transforms hood operation from a basic mechanical motion to a controlled, user-friendly experience. When you lift the hood, the integrated dampers slow the movement just enough to prevent sudden, jarring lifts, making it easier to position the hood at any angle without it slamming open. Conversely, when closing, the system gently cushions the descent, reducing the risk of accidental pinching or damage to the hood’s edge or the vehicle’s frame. This is particularly useful in windy conditions or when operating the hood single-handedly.
Compatibility is seamless, as 1643846-00-A is engineered specifically for the 2021 Model 3’s right-hand side. It aligns perfectly with existing mounting points, requiring no drilling or modification during installation. The hinge’s pivot points are precision-machined to ensure smooth rotation, with self-lubricating bushings that minimize friction and noise—so you won’t hear squeaks or creaks as the hood moves.
In terms of resilience, this hinge is built to thrive in diverse environments. It handles temperature extremes from -30°C to 70°C, ensuring reliable performance whether you’re in a snowy climate or a hot, humid region. The aluminum alloy’s natural resistance to rust, combined with the protective coating, means it stands up to road salt, rain, and UV exposure without degrading over time.
Installing the hinge is straightforward for those with basic mechanical skills. It bolts directly into the factory positions, and once secured, works in harmony with the left hinge to keep the hood aligned perfectly with the body panels—no uneven gaps or misalignment that could affect aerodynamics or aesthetics. For peace of mind, it’s designed to meet Tesla’s strict quality standards, ensuring it integrates flawlessly with the vehicle’s existing systems.
Whether you’re replacing a worn hinge or upgrading for better performance, the 1643846-00-A active right-hand hood hinge delivers the reliability, safety, and refinement that 2021 Tesla Model 3 owners demand. It’s a small component that makes a big difference in daily use, combining practicality with the innovative spirit that defines Tesla.
