I am looking at 5,000# torsions with electric brakes. Would this lower my clearance? I don't want to go any lower...too low now in my estimation. Cost is somewhat of a factor but safety is primary. I certainly don't trust my 55 year old leaf springs. Comments and suggestions welcome! Bill
Why do you want to absolutely destroy a vintage trailer.
Torsion axles operate very differently from springs.
As an example if the trailer with payload weighs 6000 pounds, then having two axles that carry 7000 pound would be fine,and, a limit.
Installing a total of 10,000 pound axles on your trailer will beat it to death in a very short time, since the axle would be grossly "UNDER LOADED".
Airstream short changed the axles ratings when they first started, and then learned that there is a window of weight that must be used.
In 1961 and 1962 Airstream used 2600 pound axles on a 30 foot trailer.
They found out that was inadequate, then changed it to 3200 pounds in 1963.
That 3200 pound rating stayed with the 30 and 31 foot trailers until the early 1980's.
At maximum, you should not use more than 3200 pound axles.
