FAQs

Q: What's the difference between a torsion axle and a leaf spring system?

A: Torsion axles use an enclosed suspension system to provide cushioning and wheel movement. Because the suspension is integrated into the axle itself, installation is quick and straightforward. With fewer moving parts, they also deliver a quieter ride. Their compact, low-maintenance design makes them ideal for light to medium-duty trailers, especially in custom builds where space-saving and ride quality are priorities.

Leaf spring systems, by contrast, use layered steel strips mounted across the axle, and provide a durable suspension that performs well in heavier-duty, utility, commercial, or off-road applications.

Both systems have their strengths, and the right choice depends on your trailer's weight, environment, and intended use.

Q: How do I know if my trailer has a torsion axle?

A: Torsion axles typically have a sealed, square or rectangular tube with trailing arms. Leaf springs use stacked metal strips and are visibly exposed.

Q: Is this axle suitable for marine or coastal use?

A: Yes, the galvanised finish helps resist corrosion in wet environments, making it well-suited for use in or near water.
