Just the spindle nuts
Just to be clear, this is just the spindle nuts and lock washer rings. 4 nuts and 2 washers -- not 4 washers like the photo shows. 2 nuts and 1 lock washer per side.Easy install, just make sure you've got the right spindle nut socket -- OTC 7158 -- and a torque wrench.This went on my 96 F250 powerstroke when I converted my auto hubs to MileMarker 449S/S manual lockout hubs.

Great product
A really well made product made right here in the USA. Also once I got my tools out it took less than ten minutes a side to install and they look great too.

Not needed on 2000 F250 despite instructions on hubs.
For 2000 F250 bought these because replacement hub (from Amazon) instructions said I needed these to install the hubs. They were NOT needed so I returned them.

Used this on my 1997 F250. Replaced the auto hubs with warn locking hubs. This kit is required to do so.
