It's easy to see why Strike King? Pro-Model? XD Series crankbaits are so popular with the pros. These medium (5XD) and large-bodied (6XD), extra-deep diving crankbaits feature a unique curved bill and balance that creates a steep dive angle, allowing them to dive deeper and faster than most other deep diving hardbaits. This unique bill also allows the XDs to track well when making contact with the bottom. Every lure in the 5XD and 6XD series also features striking finishes and free-floating rattle chambers that emit varying sound frequencies to inspire big strikes.
