Colewell Car Hood Gas Struts (also known as Bonnet Gas Springs or Lift Supports) are designed to replace the manual prop rod, providing smooth, hands-free assistance when lifting the engine cover. Unlike standard furniture struts, our automotive series is engineered to survive the harsh engine bay environment, resisting extreme heat, oil vibrations, and dust. Whether for a sedan, SUV, or heavy-duty truck, our struts ensure the hood stays securely open for safe maintenance.
