A trailer torsion axle uses a steel tube that bends and rebounds to cushion the trailer’s movement, without requiring space inside the trailer. It can be used for livestock trailers and other types of trailers, allowing for more cargo space, and is easy to replace if needed.

A trailer torsion axle is a type of axle that does not use a spring or shock absorber to cushion the travel of the trailer. Made of a spring-in-a-tube type steel tube, the trailer torsion axle bends and rebounds by turning the wheel hub assembly on a torque tube mounted inside a hollow axle tube. This style of axle does not require any space within the trailer to be used to house the suspension. The trailer’s torsion axle also allows the trailer to be towed low to the ground. This is because all movement of the trailer’s axle and suspension occurs outside of the trailer’s cargo space.

A torsion bar is a steel bar that flexes to absorb energy, such as bumps and rebounds. Used in place of a conventional spring, the torsion bar has been used in cars and light trucks for decades without failure. Trailer Torsion Axle applies torsion bar technology to a trailer axle, allowing the trailer to move smoothly without the aid of conventional springs and shock absorber packages. Another benefit of using the trailer torsion axle is that the main center section of the axle can be used to support the trailer floor. This is possible because the only part of the trailer’s torsion axle that moves is the small section of the axle attached to the wheel hub at the outboard end of the axle.

If there is ever a problem that requires replacing the trailer’s torsion axle, only the torsion bar end of the axle will need to be replaced. This component is simply disengaged from the end of the axle tube and the replacement part is slid into place and tightened. The ability to operate a trailer with very low ground clearance makes the torsion axle a perfect choice for livestock trailers, such as those used to transport cattle, hogs, and horses. Animals do not need a ramp to get into the very low trailer, in most cases.

Applying the trailer torsion axle to other types of trailers, such as car transporters and camping trailers, allows for more usable clearance between the trailer tires. With no springs and shocks taking up valuable space between the trailer tires, more space can be devoted to the cargo bed and passenger compartment. The trailer torsion axle is available in various spring rates to offset heavy loads.
