Torsion axles, according to experts, are supposed to supersede the older leaf spring axles due to their rigidity and stability. However the two axles are still locked in a war of pros and cons among boating enthusiasts. Here’s a rundown of both axles and why the leaf spring axle isn’t retiring anytime soon:

Torsion Axle

Torsion axles rely on a lot of rubber in the system for shock resistance and a smooth ride. Due to its low center of gravity, trailers with torsion axles installed can turn with the vehicle better; ideal for boating destinations that go through a lot of curves. They’re also low-maintenance as they’re attached to the trailer frame permanently and galvanized for corrosion protection.

However, due to their construction, torsion axles can’t be repaired if broken. In this case, you need to get rid of the damaged axle, which may involve some serious cutting tools, and replace it with a brand new one. Note, however, that torsion axles don’t come cheap.

Leaf Spring Axle

Leaf spring axles rely on an equalizer system where forces are equally distributed along the axle. Despite needing more maintenance than torsion axles, they’re more affordable and the more common choice among boat trailer owners. If you need to go out in the cold, leaf spring axles have the advantage since the rubber in torsion axles can be weakened by the cold. You better be ready, however, for a bumpier rideas well as less space.
