Torsion or Leaf spring axles for trailer?

Getting ready to order an Aluminum enclosed car trailer with 5200# axles. Trailer weight is 2700# whereas the same steel trailer is #4600. Which type axle is going to give the best duty?

with 7k's. Like the torsion best, much smoother ride. Had a
longer waranty as well.
What Is the Difference Between Standard & Torsion Trailer Axles?
Torsion axles are suitable for lighter loads.
There are basically two types of common trailer axles. Torsion axles use a rubber spring for suspension, while standard leaf spring axles use a metal spring. There are many variations on the leaf spring axle, but they have essentially the same properties. The choice between a torsion and leaf spring axle really depends on the size and weight of your trailer, and your particular needs.
Size
Rubber torsion trailer axles are more compact than other types of trailer axles, so they save space and weight on a small trailer. Common leaf spring axles are generally larger and heavier.
Smoothness
The rubber elastomer springs used in torsion axles help smooth out the ride and absorb a lot of the bumps. Torsion axles are also quieter than leaf spring axles, which tend to squeak every time the spring bounces.
Load Limit
Because standard axles are bigger and tougher than torsion axles, they are able to hold more weight and support a larger trailer. Torsion axles are smaller partly because the design allows it, but also because they simply cannot support large trailers. Torsion axles do not spread the weight around the frame as much as leaf spring axles, so it is harder on the trailer. In a multiple axle configuration, standard axles share the load with each other, while torsion axles remain independent. This means that when you pass over a bump with a multiple torsion axle trailer, one of the axles is under a lot of stress while the other is under relatively little.
Lifespan
The rubber in torsion axles does not age well. Over a period of years the rubber elastomer hardens, becomes brittle and eventually cracks. Standard axles eventually wear out as well, but they normally last much longer than torsion axles.
If you go with torsion go with Dexter. I designed and built the machinery for one company which I won't mention. I know every thing a person would want to know about torsion I think. Email me if you have a question and I will answer it to the best of my ability. There is one company you want to stay away from out there.
They are Dexter axles, not the chinese or other brand. In fact the trailer company is in Elkhart along with Dexter. I read Dexter's webpage that said the torsions bolt or clamp to the frame. I have no idea how a leaf spring axle would connect to an aluminum frame. I know Featherlite uses torsions on their trailers.

Leaf spring axles would probably connect to an aluminum frame the same way they connect to a steel frame: with a spring pivot at one end, and a hanger/shackle at the other.
Torsion Axles are weaker against Cornering Loads, and under Static or Dynamic (Like going over A Curb or Limb) Loads.
The Old Straight Axle, With Semi-Elliptical Springs is a Tried-And-True Design, with features that tend to Fail in Generally Beneficial ways. Makes for more ground Clearance.

Torsion if you have the choice.

Spoke with two dealers yesterday. They are very close to the same price for exact units. 22K dollar Featherlite trailers are out. Two other companies build similar trailers as Featherlites and I am going with one of those with Dexter torsion axles. Torsion axles run independant of one another. IF tires fail, spare fails I can possibly get home on one axle. Spring axles drop down and eliminate moving the trailer if a malfuction occurs.
