If you’re in the market for a new boat trailer axle, you’ve probably noticed that there are quite a few axle types available. If the choice of axle types has left you confused, reading on below will give you a better understanding of their differences and help you make an informed decision about your purchase.

The straight axle is simply a straight bar that stretches between the trailer’s wheels. They are typically constructed from a heavier metal to counteract the mechanical forces that cause it to bow under the weight of the boat. This choice of material provides the necessary structural rigidity that would otherwise be absent in a straight bar at the cost of weight, and consequently, gas mileage.

A dropped axle is similar in design to a straight axle but with a bend, or drop, in the bar at the center of the axle. This allows the boat to sit lower in a dropped axle and, coupled with the weight reduction offered by its engineered shape, results in better gas mileage.

The lower profile also allows you to launch the boat without having to go as far down the launch ramp as you would with a straight axle.

A far more engineered approach to axle design, the torsion axle promises to provide a significantly smoother ride over straight and dropped axles. Torsion axles work in a similar way to independent rear suspension on cars and lessen how much the load bounces around while driving.
