The 1963-1972 GM Car Heavy Duty Steel Hood Hinge Spring with 28 Coils is a high-tension replacement designed to support steel hoods on a wide range of classic GM vehicles. Built from rugged steel and engineered to match the tension and dimensions of original GM springs, this component ensures smooth, safe hood operation when paired with factory or reproduction hinges. The 28-coil design delivers consistent lift and hold, preventing premature sagging or stress on the hinge assembly. Whether replacing a fatigued spring or completing a full hood mechanism rebuild, this spring is essential for long-term reliability.
Installation:
Difficulty: 4/5 – High spring tension requires caution and specialty tools.
Instructions: Use a proper spring installation/removal tool or heavy-duty vise grips to safely extend the spring. Hook one end to the hinge body and stretch to attach the opposite end to the hinge arm. Always wear safety gear and work slowly to prevent injury. Repeat for the opposite side. Test hood movement to ensure smooth and balanced operation.
