Frequently Asked Questions (FAQs)

1. Are heavy duty springs worth it?

Heavy-duty springs are worth it if you regularly haul extremely heavy loads. They are stronger and more resistant to bending, providing a better ride and preventing the springs from bottoming out.

2. What are the different types of heavy duty springs?

There are several types of heavy-duty springs, including compression, torsion, tension, disc, wave, clock, volute, power, constant force, and garter springs. Each type serves different purposes and applications.

3. What is the difference between heavy duty and standard coil springs?

Heavy-duty coil springs are shorter than standard springs to prevent the vehicle from sitting too high when unloaded. They are also 15-30% stronger than standard springs, depending on the vehicle.

4. Does heavy-duty springs help towing?

Yes, heavy-duty leaf springs can handle heavier loads without causing damage or excessive wear. By increasing the load capacity of your vehicle, heavy-duty springs allow you to tow greater loads and carry more cargo.

5. Are thicker springs stronger?
