Why Do Weight Ratings of 2-Inch Hitch Balls Vary Between Fixed and Adjustable Types

Expert Reply:

The B&W Tow & Stow Adjustable 3-Ball Mount # BWTS20049B has a 2-inch ball rated for 7500-lbs. You are right that standard individual 2-inch hitch balls can carry much higher ratings, such as Curt 2-inch ball # A-90 which is rated for 10K.

All of our standard 2-inch hitch balls are shown on the linked page. These carry class ratings from Class I all the way up to Class V, as with the Curt ball # A-90.

The lower ratings with any adjustable multi-ball type ball mount result from the additional components and connection points. Single balls on a standard fixed ball mount can offer higher ratings since they have fewer components.
