Why are Hitches for a 2005 Toyota Highlander Not Rated for Weight Distribution

Question:

On web page listing the available hitches for the 2005 Toyota Highlander you list three Class III and in the specifications it says not rated for weight distribution systems. Can you explain why they are not rated for WD when they are Class III and what hitch is rated for WD?

You're correct. A class III hitch is typically rated for use with weight distribution. However, the Highlnder is one of a few exceptions.

According to our hitch manufacturers, a hitch installed on a 2005 Highlander isn't compatible with weight distribution. This is because the vehicle uses unibody construction instead of a conventional frame. A weight distribution system applies a great deal of leverage and torque to the vehicle frame (much more than what would be applied in a normal towing situation), and it is the opinion of the hitch manufacturers that the structures on the underside of the vehicle that the hitch attaches to are not strong enough to safely withstand the additional stresses using weight distribution would place upon them.

Because of this, there are no hitches for the 2005 Highlander that would be compatible with a weight distribution system.
