FAQs
Q: What is progressive spring compression?
A: Unlike linear springs that compress at a constant rate, a progressive spring features leaves designed to increase stiffness as they compress. This design allows the trailer spring to provide a smoother ride under light loads while offering greater support under heavier loads. As a result, it delivers better control across varying conditions and helps prevent excessive sag. This dual-rate behaviour allows your trailer to handle a wider range of load conditions without sacrificing control, ride quality, or safety. It also helps reduce wear on other suspension components and minimises the risk of bottoming out under heavy loads.
Q: What is Zinctech coating?
A: Zinctech is a specialised corrosion-resistant zinc coating applied to steel components. It offers strong protection against rust, extending the life of springs and hardware in outdoor environments.
Q: Why is the second leaf longer?
A: A longer second leaf supports the main leaf, reducing stress on the eye area and extending the trailer spring's service life.
Q: What are anti-rattle leaves?
A: Anti-rattle leaves are designed to minimise movement and noise in a leaf spring suspension system. At the slipper end, the spring leaves are spread out (or "fanned") rather than stacked tightly together. This creates a snug fit inside the slipper, which helps reduce rattling, wear, and vibration during towing.
Q: Can I get axles with this kit?
Yes. You can add ready-made axles or custom fabricated axles to your order. To get axles made to your specifications, please visit: https://www.treadway.co.nz/Resources/Axle-Fabrication.html
