Trailer Axle Leaf Springs
Some Key Leaf Spring Questions
1. How do I choose a leaf spring for my trailer?
Trailer leaf springs need to be selected based on the axle weight rating and the spring type (slipper or double-eye), length and width dimensions. Axles usually have a sticker or plate on them that provides their weight rating. It is important to note a few things about replacement springs.
2. How long do trailer leaf springs last?
Regular boat trailer leaf springs last two or three years on average. **Remember, when upgrading to torsion axles from leaf springs, plan on raising your boat trailer fenders up a few inches to give your trailer tires the clearance they need.
3. Why do trailer leaf springs break?
The number one cause of a leaf spring breaking is an overloaded truck or trailer. Do not overload your vehicle and keep the weight within the capacity limitation of the leaf springs. Inspect your leaf springs for cracks so that you can replace a leaf spring before it fails.
4. How do you know if your trailer leaf springs are bad?
Trailer springs should always be inspected for cracks and breakage to avoid failure of the trailer spring. Cracks typically appear near the philister bolt and near the bolt’s eye that connects your spring to your hanger. Anytime you see a crack or break in the spring, it is time to replace them.
5. How do I make my leaf springs ride smoother?
Suspension softening typically consists of two steps. To begin, you replace the pre-existing shock absorbers with a lighter set. These soft absorbers are primarily designed for comfort. Second, the vehicle’s springs can be replaced with a softer pair — in other words, lower-rated leaf springs.
