Question:
What advantage does a solid shank give?

When the shank of a ball mount or hitch-mount accessory - say a bike rack for example - is solid rather than hollow this typically means it will be stronger. It also means it will be heavier.
The Brophy Ball Mount # BH20 has a solid steel shank which is part of why it has a very substantial 10,000-lb weight rating. The roughly similar Curt ball mount # C45010 offers a 7500-lb weight rating; Even though it is not a solid shank, it does have a very thick platform for our ball to attach.
Hollow shanks also allow use of a locking anti-rattle device like # 63232 which cannot be used on a ball mount with a solid shank.
