Classes, receiver sizes, and matching hitch ratings to the trailer.

A reducer sleeve lets a smaller shank fit a larger receiver. Convenient for light racks — risky when you ignore the reduced rating. Prefer a native-fit accessory when the load is heavy.

Light bike racks on a two-inch tube can use a rated reducer into a one-and-one-quarter shank when the accessory rating still covers the load. Pin through the sleeve and shank as designed.
Loaded e-bike racks, heavy cargo, and towing mounts deserve native shank sizes. The reducer capacity often becomes the new lowest number in the chain.
Confirm ratings and fit notes on each product page before you order.
