As you climb up the Club Divisions, your Club will unlock better and better perks, such as:

Additional team Loadouts – Increases the number of Loadouts you can store and swap between

Flag bonuses – Increases the number of Flags that you can win in a Duel

Bucks bonuses – Increases the percentage of Bucks that you find in Crates. This excludes Bucks rewards from offers, Spinners, etc.

Perks only apply to your Club, and you cannot take them with you if you leave. They also depend on which Club division your Club is currently in, and can diminish if you get demoted to lower Divisions.
