The WARN Premium Hub is a no-compromise hub designed for the hardcore off-roader or truck owner who will accept nothing less than the industry standard in performance. The all metal construction and ZA Alloy dial ensure years of reliable functioning. This dial requires a full 9/10ths of a turn to ensure positive engagement of the inner drive gear to the clutch ring. To make sure they stay engaged, WARN premium hubs use a thick internal wave spring and heavy dial detents. We know our premium hubs will be used hard, so we build them to last. All WARN Premium Hubs feature: 9/10 turn dial for robust engagement/disengagement Heavy detents for positive engagement Wave spring technology increases reliability over standard coil springs. All metal construction ZA Alloy dial with dual seals keep contaminants.
