How many miles does a coil spring last?
Coil springs are a critical component of your vehicle's suspension system, responsible for absorbing shocks and maintaining proper ride height. As a car owner, understanding the lifespan of coil springs can help you plan for maintenance and avoid unexpected repairs. In this article, we’ll explore how long coil springs typically last, factors that affect their longevity, and signs that it might be time for a replacement.
Typical Lifespan of Coil Springs
On average, coil springs are designed to last around 100,000 miles under normal driving conditions. However, this lifespan can vary significantly depending on factors such as the type of vehicle, driving habits, and road conditions. For example, vehicles that frequently carry heavy loads or are driven on rough terrain may experience faster wear and tear on their coil springs.
Factors That Affect Coil Spring Longevity
Several factors can influence how long your coil springs last. Here are the most common ones:
- Driving Conditions: Regularly driving on rough or uneven roads can put extra stress on your coil springs, causing them to wear out more quickly.
- Vehicle Load: Carrying heavy loads or towing can compress the springs more than usual, leading to premature wear.
- Climate: Exposure to moisture, road salt, and extreme temperatures can cause rust and corrosion, which weaken the springs over time.
- Quality of the Springs: Higher-quality coil springs made from durable materials tend to last longer than cheaper alternatives.
Signs Your Coil Springs May Need Replacement
It’s important to recognize the warning signs of worn or damaged coil springs to ensure your vehicle remains safe to drive. Look out for the following symptoms:
- Uneven Ride Height: If one corner of your car sits lower than the others, it could indicate a broken or sagging coil spring.
- Excessive Bouncing: A worn coil spring may struggle to absorb shocks, leading to a bumpy or uncomfortable ride.
- Clunking Noises: Damaged springs can produce clunking or creaking sounds, especially when driving over bumps.
- Visible Damage: Inspect your coil springs for signs of rust, cracks, or breaks.
When to Replace Your Coil Springs
If you notice any of the signs mentioned above, it’s crucial to have your coil springs inspected by a professional mechanic. Even if your springs appear to be in good condition, it’s a good idea to have them checked during routine suspension maintenance, especially if your vehicle has surpassed the 100,000-mile mark.

Frequently Asked Questions
How often should I replace coil springs?
There really is no set timeframe at which coil springs expire. A lot of coils last for the life of a vehicle, while others break down sooner.
How do I know if my coil springs are worn out?
Here are common symptoms indicating that coil springs might be damaged or broken: Uneven ride height: The car will be higher on one side or lower in one of the four corners. Loud suspension: This is usually a clunking, squeaking or creaking sound after the car travels over a bump or imperfection on the road.
Will new coil springs improve ride?
In conclusion, springs have a significant impact on the ride quality of a vehicle. Coil springs generally offer a smoother and more comfortable ride, with the ability to be adjusted for different needs.
Do coil springs affect alignment?
It's important to match OE spec by application when it comes to spring designs to help restore OE ride height specifications assigned to each vehicle. Even a 15% reduction in ride height can cause the vehicle to noticeably sag and may affect wheel alignment which could result in accelerated tire wear.
Do coil springs weaken over time?
Coil springs lose their strength over time for various reasons, such as aging and environmental factors. However, with regular maintenance checks and proper storage conditions for unused coil springs, it is possible to prolong their lifespan significantly.
What happen if you drive with bad coil spring?
Excessive tyre wear: A broken coil spring can cause uneven pressure on the tyres, leading to accelerated wear. Increased braking distance: Due to poor handling and misalignment, stopping your car in time becomes more difficult, potentially increasing your braking distance.
What is the life expectancy of a coil spring?
60,000 to 90,000 miles
Typically coil springs last 60,000 to 90,000 miles before they need to be replaced. However, they can break due to: Corrosion – To do their job, coil springs are constantly expanding and compressing. This action causes the plastic coating that protects the wire to crack – exposing it to the elements.
How often do coil springs need to be replaced?
There really is no set timeframe at which coil springs expire. A lot of coils last for the life of a vehicle, while others break down sooner.
Do coil springs ever go bad?
Even though coil springs are made to be quite durable, there is a possibility that they could potentially wear out or fatigue over time. This could be due to how the vehicle was used, or if overly heavy loads were hauled or towed with the vehicle.
Can I replace just one coil spring?
Can I replace just one coil spring? Coil springs should be replaced as a pair to ensure safe driving and prevent accidents caused by damaged or broken springs.
