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

Expert Reply:

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.
