Review on Mile Marker 449S Lock Pair by Tim Beckett

Firstly they arrived a day early which is always good. I'm not sure if it's MM or Revane. They appear to be of very good quality. As others have said, very simple setup. Probably 30 minutes either way. The hardest part was just aligning the splines, that was easy too. just be patient I ordered them to finally get rid of the horrible Ford vacuum hubs that were always a problem. She. I rarely use 4x4s so getting out and locking/unlocking isn't a problem. I lubricated the screws with blue Loctite. I would give 5 stars but I only installed them yesterday so expect durability. So far so good, nice and quiet. MM has a video if you click on specs on Revain.
