Why Are There Both Round and Square Trailer Axles Used on RVs
Updated 11/19/2014 | Published 11/18/2014
Question:
Just making a statement, about 98 of all RV trailer frames have round axles tubes . About 98 of trailer axles you see on the internet for repairs and the building of new axles are square or box tubes. Why?

Helpful Expert Reply:
Most of the OEM axles installed in RVs and most of the replacement axles we offer are indeed round in cross section. We do offer some square stub spindles for use on square axles, such as # TRU97FR, but these are usually limited to lower capacities like utility trailer applications. We do not have the ability to ship high-capacity axles due to their weight.
