Mile Marker hubs manually lock your vehicle into 4-wheel drive and are built last through all weather and terrain. The 426 hubs are an easy-to-install replacement for vacuum locking hubs on older Ford Rangers ('98 – '00) and Mazda's (B3000/B4000 '01-'08). Construction of this hub features a nylon reinforced dial and a brushed aluminum jacket. Use fitment and User guide for exact fitment questions. If converting from automatic hubs, a nut conversion kit is required on some applications.
