If you trailer is fitted with torsion springs and they need replacing, you should consider replacing them with leaf springs. Below is a guide to the benefits of installing leaf springs onto your trailer's suspension system.
Leaf springs help to preserve your trailer tyres
If you own a trailer that has multiple axles, then leaf springs are the right choice for you. A leaf spring will flex and adjust to accommodate whatever weight is loaded onto the trailer and will balance as the tyres gain traction on the road surface. If you are going over uneven ground, each leaf spring will adjust to ensure that all the tyres on your trailer are in full contact with the ground. The full contact will make sure that you have control over the trailer and that the tyres will wear evenly. Torsion springs cannot adjust in this coordinated way, which can lead to uneven tyre wear on your trailer.
Leaf springs are better when the trailer is in storage
Many people do not use their trailer on a regular basis. If you store your trailer away for weeks or months at a time on an uneven surface, you should consider installing leaf springs. When the trailer is left parked on an uneven surface, pressure is placed on the suspension. Because each spring within a leaf spring operates independently, it can easily balance the different pressures being placed on each tyre. A torsion spring is more likely to be damaged if your trailer is parked on an uneven surface for an extended period of time as it cannot balance the pressure in the same way.
Leaf springs are reliable
Because a leaf spring doesn't contain as many moving parts as a torsion spring, it is less likely to suffer a failure. Leaf springs are also better at supporting heavy loads when compared to torsion springs. Torsion springs concentrate the weight of the trailer onto the small area of the frame. A leaf spring will spread the load evenly over a larger surface.
The lifespan of the suspension unit on your trailer will be largely dictated by the type of ground you use it on and the type of suspension springs you have fitted. If you would like more information about the benefits of installing leaf springs on your trailer, you should contact a trailer repair and servicing specialist. They will be able to assess which type of spring is best for your trailer.
