Just thought ld let everyone know warn came out with locking hubs for 2005 to current super dutys. Part number 95070 they come in chrome or black. I had one of my stock ones that wouldn't unlock last winter, so I thought this was a good opportunity to upgrade. I purchased a set from summit racing and so far they work great. Nothing plastic like oem, their very well made and easy to install.

 

Are they autolock like the factory or do you have to turn them in?

 

My factory hubs are manual.

 

they are manual hubs. The internal parts are much beefier than the factory parts. Ford wanted $600 for one side these were under $400 for the pair. Plus they are completely serviceable unlike the factory part that is all one piece.
