Coil Spring vs Leaf Spring Suspension on Vans
Coil springs offer comfort and handling, while leaf springs provide load-carrying capacity for heavy commercial vehicles.
Most modern vans use coil springs at the front and leaf springs at the rear to balance ride quality with load capacity. Leaf springs are simple, robust, and can carry heavy loads without sagging, but they can break under extreme stress or corrosion. Coil springs offer a more comfortable ride and better handling but can snap if the vehicle is frequently overloaded or driven on poor roads. A broken coil spring causes the vehicle to sit lower on one corner and may damage the tyre. A broken leaf spring causes a noticeable drop in ride height and severe handling instability.
Key takeaways
- Leaf springs provide load capacity for heavily laden vans
- Broken coil springs cause uneven ride height and tyre clearance issues
- A snapped leaf spring makes the vehicle unstable and dangerous to drive
