Mile Marker 549 Pair of Premium Manual Locking Hubs fits 2005 2020 F250 F350 F450 F550 - Replaces Original Equipment Manual or Automatic Hubs - High Performance - Durable Metal Construction

There is no question when you get these in your hand that they are heavy duty and will last a lifetime. Highly recommend over the stock parts and well worth the money.

The plastic cam is not holding up It keeps cracking

The box says "Fits 2005 & Newer Super Duty Trucks", but it's not even close. Spline pattern/shape is wrong. I have no idea what this fits, and we pulled the locking hubs from another truck to make sure it wasn't something messed with my hubs, same issue. Of course I'm outside my return window. Anyone else have this happen?

These worked for a while, but got tougher and tougher to engage. Driver side I had to start using vise-grips to engage. Passenger side the plastic cam inside broke. Drivers side, the plastic cam melted from the spring spinning. People keep commenting how these are so great because they don’t have plastic in them, but they do. Lifetime warranty, but Mile Marker wouldn’t stand behind the warranty because I purchased from a certain online retailer. Very disappointed in their customer service at Mile Marker. Probably will never buy another product from them again.

These look strong and durable. Since I haven't tested them yet I can not comment positively. I do have a concern with them. They are difficult to manually engage. One or the other will usually lock on the first try but to get the other to lock it is necessary to put the truck in neutral then rock it back and forth till it locks. I phoned the manufacture (left a message) then emailed asking them for their input. It has now been over 2 weeks with no reply

I have used Mile Marker for years in some off-road toys and have always been happy. Their quality has always been second to none. I will be installing these in a 2009 F-250 and am so glad to get rid of the cheap plastic faced OEM ones.This pair is, without a doubt, some high-quality all-metal hubs. You can feel it from the actual weight of the parts as well as the quality of construction. I do not doubt the waterproof and corrosion claims stated, based on previous experience with the brand and its quality.I am looking forward to installing this weekend.

This hub is functional but it makes wheels look customized. They're made to take a beating and still perform well. If you check stores, you'll find that this item can get very pricey. This part is easy to install if you want to save yourself some money. It's a good deal.Thanks so much for taking the time to read this review. I hope the information that I've provided makes your decision a little easier.

I installed these on my 2009 F350 over the weekend. They were a direct replacement for the tired auto locking hubs and I had no issues getting them in. They locked up nicely and they look pretty good too. The all metal construction seems like a remarked improvement over the plastic caps on the OEM hubs. I am hoping to see them hold up to Michigan winters over time.

Price is great, made it USA, great quality, comes with everything needed and will last way longer then stock.

Changing to these style of hubs, very impressed with the setup and install. Great system for hubs. Great customer service as well.
