https://www.jimaforging.com/products/3g8-817-977-978-trunk-lid-reinforced-hinge.html The hinge for trunk refers to a hinge structure that uses elastic elements to balance the gravity of the trunk lid when it is opened and closed. Because the balance hinge has the advantages of simple structure, sufficient strength, reliability and durability, most models, especially mid- to low-end models, basically adopt this structure of hinge, and its elastic element adopts torsion bar. During the use of the trunk lid, it is generally required that after the opening device is activated, it can automatically pop up to a certain height, and it must remain stationary in the half-open (certain opening angle) state to prevent it from falling and injuring people. At the same time, it must be in the most open position. It has enough holding power to prevent it from falling and closing due to wind force. Features of 3G8 817 977 978 trunk lid hinge Enhanced Durability: The soft close hinge for trunk is designed and constructed using durable materials and robust mechanisms, ensuring long-lasting performance and resistance to wear and tear. Increased Load-bearing Capacity: The 64 impala trunk hinges is engineered to handle heavier loads and withstand the pressure and stress exerted on the luggage trunk cover, allowing for secure and reliable operation even when the trunk is fully loaded. Smooth Operation: The boot lid hinges is designed to provide smooth and effortless opening and closing of the luggage trunk cover. These metal auto parts minimize friction and ensure a seamless user experience when accessing or stowing items in the trunk.
