Receiver opening size decides which shanks fit. One and one quarter inch is common on lighter cars and crossovers. Two inch dominates trucks, SUVs, and most Canadian accessory docks. Measure the tube, then shop mounts and racks that match.

| Opening | Common on | Typical accessories |
|---|---|---|
| One and one quarter inch | Cars, compact crossovers, Class 1 and Class 2 hitches | Light mounts, light racks within rating |
| Two inch | Most trucks, SUVs, Class 3 and many Class 4 hitches | Everyday mounts, bike racks, cargo carriers, WD shanks |
Some heavy-duty tubes use two and one half inch openings. Read the stamp. Never assume class and opening always travel together — confirm both on the product page.
A reducer sleeve can let a smaller shank into a larger tube. Capacity often drops to the reducer rating. Prefer a native-fit accessory when you can, especially for e-bike racks and loaded cargo carriers.
Confirm ratings and fit notes on each product page before you order.
