i have had these for 6 years and there still perfect. if they stick you clean and re oil them. couldn't ask for a nicer hub. if you get the ford oring and put it behind the hub it will never fail the mm o ring is too small
M/M Junk

These hub lockouts worked ok for about 6 months then they started sticking. Granted I bought them from O'Reilys but they're the same part. I replaced them with the Warn lockouts and I haven't looked back. Save yourself the headache, these are a waste of money.
Great locking hubs

I got these hubs to replace failed warn hubs on my super duty, they are very strong and reliable and don't stick like the warns do. They are clearly better built hubs then warn and there cheaper!! Takes 5 mins to install and comes with everthing you need to install them. Also got to say that XDP has the best costumer service around!
