Exceeding industry standards, Mile Marker manual hubs provide convenience and efficiency for the extreme off-roader or truck owner expecting the best performance. The all metal construction and heavy duty dial are just part of what makes these hubs endure years of use. The dial requires a 1/4 turn to achieve positive engagement of the inner drive gear to the clutch ring. With a heavy duty internal spring and heavy dial detents, the 449SS locking hub is sure to stay engaged. The 449SS Manual Hub Set comes with 2 hubs to make a full set and is for use with 30 spline axles. There are many vehicle applications that can be referenced on our application guide, including Ford F Series Super Duty 1979 - 2004. Mile Marker products have been trusted by off-road enthusiasts, powersport professionals and even by the United States military for almost 30 years. *** If replacing certain models of automatic 3 hole cap screw hubs, a spindle nut conversion kit may be required. Mile Marker part number 95-32721 *** Review: Easy upgrade to cheap plastic OEM parts on '01 Excursion - After going through several pairs of the 'OEM' replacements for the vacuum-operated 'automatic' 4x4 front hub locks, I saw these and decided to pay a few extra dollars so I never have to replace the hub locks EVER again. These are SOLID, an obvious upgrade to the existing plastic-filled lockers that came on these trucks. I can get out and manually lock my hubs when I need 4x4, so it's not a great loss to have actual metal pieces doing the engaging action as a trade off. Installation was cake - it took more time to remove the siezed and broken OEM unit than it did to clean out the hub and slide these into place. It shoulhd have taken me less than 10 minutes if not for the stubborness of the old parts. Some people suggest using blue thread lock on the 6 bolts that keep everything together, but I haven't had any back out at all after several hundred miles so just tighten them up pretty good - they're literally the only parts you really have to do anything with, as everything else just slides into place. The way these are designed, you can see the interals and how everything works, and you'll know you've made the right choice here. I'm looking for shorter center caps for my factory rims, since these units are shorter than OEM lockers, but it's barely noticable so NBD. If you're looking for reliable, light-medium 4x4 upgrade bits, these are a great start to a killer off-road rig.
