Often asked: What Is A Torsion Axle On A Boat Trailer?

Torsion axles are a type of suspension for trailers that eliminate the need for leaf springs. They work by flexing rubber cords in the axle tube to create torsion and flex creating suspension for the trailer.

Are torsion axles good for boat trailers?

Having a good quality axle means you are worry-free. Torsion axles offer a low maintenance, reliable, quiet, smooth ride. HSI Duratek torsion axles make it simple to have peace-of-mind while trailer towing. The boom in usage can be attributed to the many benefits that torsion axles offer over standard spring axles.

How does a boat trailer torsion axle work?

Torsion axles work by using rubber cords or cartridges inside the axle tube to handle suspension travel and shock absorption. Torsion axles do not use leaf springs, but instead the compression of the rubber to supply the suspension support needed. Each wheel works independently from one another.

Are torsion axles better than springs?

Torsion trailer axles offer a smoother ride and less maintenance. Leaf springs are more durable, less expensive and far easier to replace parts on. Whichever you choose, you’ll see the best results by properly loading your trailer with the aim of getting the most wear out of the system you pick.

How long do torsion axles last on a trailer?

Subject: RE: Rubber Torsion Axle Life Expectancy? the lifespan is 15-20 years. no matter how many miles towed or how stored (weight off frame, etc.)

What is the advantage of a torsion axle?

Torsion axles are mounted directly to the frame which means fewer moving parts compared to spring suspensions, resulting in a smoother shock action. This stiffens the frame, reducing flex. This system is also less likely to corrode because the axle tube is galvanized inside and out.

Do trailer torsion axles wear out?

Helpful Expert Reply: It is certainly possible for any axle to wear out enough over time to need replacing. Since the suspension is built into a torsion axle if the suspension part was to wear out pretty much the only solution would be to replace the axle.

How do you maintain a torsion axle?

Torsion Axle Maintenance Torsion axles do not require any regular maintenance, unlike springs that need constant review for worn or loose parts. Spring axles must be checked regularly to make sure the spring surfaces are not corroded, creating a weak point in the suspension.

Can a torsion axle be repaired?

Torsion axles use internal rubber cords to provide the suspension motion and they really are not practical to repair/rebuild. Certainly any axle that was damaged in an accident should be replaced purely for safety reasons.

Can you replace spindle on torsion axle?

If you have an Eliminator Torsion axle you can replace the spindle. If the torsion arm is exposed on the backside, you can place the castle nut back on the spindle so that it is even with the end of the spindle, and then hitting the rear of the spindle to force the spindle loose.

Do torsion axles need shocks?

Torsion axles do not suffer from the same harmonics of spring-rate as other axles do, so they rarely need shock absorbers.

How do you inspect a torsion axle?

The first test is to jack up each side of the trailer and watch to see if the wheel moves down as weight is removed from that side, if on either side the wheel does not drop at least 1½” the axle needs replacing.

When should you replace trailer axle?

If the wheel hubs have not been serviced or replaced recently, show visible signs of wear or damage, or are making noises indicative of worn bearings, this would be a good time to replace them since they have to be removed anyway. With all new parts in hand, it is now time to install the axle.
