Warn Premium Manual Hubs

Warn's premium manual hubs feature a no-compromise design for the hardcore off-roader or truck owner who will accept nothing less than the industry standard in performance. Their all-metal construction and ZA alloy dial ensure years of reliable functioning. The dial requires a full 9/10 of a turn to ensure positive engagement of the inner drive gear to the clutch ring. To make sure that they stay engaged, Warn premium hubs use a thick internal wave spring and heavy dial detents.
