What are Hood Springs?

Hood springs are a proven method for making the hoods on heavy-duty trucks more manageable. As the hood is opened the spring will help to slow the hood once it has passed its balance point. The hood springs prevent the hood from slamming open with its full weight and causing damage to the bodywork. Hood springs work in conjunction with hood cables to limit the full open travel of the hood to a position that allows the hood to stay open on its own but does not damage the hood or the bumper.

Why do Hood Springs Fail?

As hood springs wear, they may lose their strength and allow the hood to open more freely. This can put extra stress on the mounting points for the springs and for the cables. If the hood is caught by the wind and opened with great force it could cause some of these mounting points to be ripped from the truck. Over time metal fatigue will cause the springs to break and you will lose all assistance with the hood. Fiberglass may seem light but when something the size of a truck’s hood is being propelled by the wind and pulling you along, it is hard to slow it down.

How Do I Identify the Correct Replacement Hood Spring?

Hood springs should be replaced before they reach the point of breaking and if you are pre-tripping your truck daily it will be easy to tell when the springs are wearing out. Besides the feel of the hood, an easy way to tell visually is if the springs no longer fully rebound when you are closing the hood. This will leave gaps in the coil when there is no weight on them. This shows that the coil is fatigued and can no longer hold the tension that it used to.

Finding replacement hood springs can be done using the OEM numbers for the original springs. On older trucks, it may not be as easy to get part number using the VIN, so it is possible to find some hood springs by measurements.

Total length – Total length is the length of the entire hood spring assembly from end to end when it is relaxed and retracted. Hood springs will have hooks or loops for attachment to mounts on the hood and body. The total length will include the hooks in the measurement. Again, if the spring that is being replaced is worn out and stretched, you will need to estimate how long the total length would have been when it was new.

Spring length – Spring length is measured as the total length of the retracted coil. On a worn-out spring that is stretched out, this measurement will not be exact because you will have to estimate the length of the coil when it is retracted.
Spring OD- The hood spring outer diameter is measured on the outside of the coiled portion of the spring. The outer diameter of the spring will relate to the strength of the spring when combined with the wire diameter.
Wire Size – The wire size will be shown on some hood springs. The wire diameter relates directly to how much pulling force the spring will have.
Color - The color of the hood spring will match the OEM color to aide in identification purposes.
