Coil Spring Repair & Service
Also called linear rate coils, constant rate coils make driving more predictable for the driver than variable rate coils. These springs have one defined spring rate per inch of compression. So, if you had a 12-inch-long 300lb/in constant rate spring, it would take about 300 pounds to compress it one inch. It would take another 300 pounds to deflect another inch, and so on until the spring goes solid.
Knowing the linearity of rate makes it easy to set up a vehicle’s ride height, since it makes it easy to calculate any given spring length at ride height. In general, performance-oriented springs that are designed for road racing have a linear rate because the consistent nature of the constant rate spring coil stabilizes the car and optimizes traction for the driver.
For Every Application
Cargo, Heavy Duty and Variable Rate Coils
Also called progressive rate coils, variable rate coils give the suspension more compliance when the vehicle drives over rough surfaces or different uses. Variable rate springs are designed with an initially low spring rate that increases as the spring gets compressed. So, if you had a 12-inch-long variable rate spring it might take 300 pounds to deflect one inch but the second, third and fourth inch will take more to deflect. It may take another 400 pounds to compress the second inch, an additional 500 pounds for the third inch and so on until the spring goes solid.
Variable rate coils are more common in vehicles that do off-road racing than in road racing vehicles that do road racing. They can be tuned to come into effect after a car lands a jump during an off-road race. They are also great for trucks hauling heavy loads sometimes and being empty at other times.
Coil Spring Inspection
If you suspect your coil spring is going bad, bring it in for an inspection. Driving with bad coil springs can be dangerous. Your vehicle’s movements can become abrupt and unstable. It could also lead to more costly repairs down the road, like replacing an axle.
Here are some signs that your coil springs are going bad and you should bring your vehicle in for a coil spring inspection:
1. Your vehicle sags or leans
Coil springs balance and support the weight of your vehicle. If your springs go bad, your vehicle ride height will start to decrease and your vehicle will appear to sag or lean. You’ll especially notice worn coil springs when you’re your vehicle is loaded and the ride height changes noticeably.
Coil springs are checked on a flat surface by taking measurements at specific body and frame points. A lot of time you can visually see sags or leans but in many cases measurement and visual inspection are the most accurate way to inspect coil springs. When a vehicle leans there is a side to side difference in ride height. If one side is sagging more than the other, it might mean that the coil on one side is worn more than the other. If that’s the case, you will still need to replace the coils on both sides. A sag is present when there is a slight tilt downward in between your front and rear bumpers.
You might also notice your vehicle sagging when the vehicle is empty. In most cases vehicle come from the factory.5 to 2” higher in the back. Your vehicle should have a bit of a lift in the rear when it’s empty. If you notice any sagging when your vehicle is empty, then you probably have a problem in your suspension and should bring it in for an inspection.
If the vehicle sags or leans when loaded the coil spring may be worn out or the problem may be it is simply overloaded and requires a heavy duty or custom coil spring. With 25 year of coil spring experience we can provide solutions for any coil spring issue.
2. Your vehicle bottoms out
When coils fail completely the symptom of bottoming out is usually present. Most vehicle have fail safe parts called bump stops, installed from the factory, which prevent major damage in the event coil springs fail. If you ride is harsh and you are experiencing the sensation of bottoming out, bring the vehicle in immediately for an inspection.
3. Your vehicle makes loud noises over bumps
Anytime your vehicle makes an unsettling noise, you should bring it in for an inspection. But when it comes to coil springs, you should be especially concerned. Coil springs in combination with shocks and tire absorb road shock . With good coil springs and shocks you shouldn’t notice any loud noises over bumps as you drive. If you start noticing your vehicle becoming louder and louder over time, it could be because of bad coil springs. You might especially notice additional noise when you hit a pot hole or speed bump, since these and other road obstructions make coil spring compress and rebound more which magnify any issue that are present.
In addition to the noise, you might start feeling your vehicle become less comfortable to drive as it becomes more unbalanced and unstable as your coil springs go bad. If you’re experiencing loud noises, harshness or a extreme feeling of softness as you drive, bring your vehicle in for a coil spring inspection.
