            Works great easy install for my gear guy. He told me I needed these to fully rebuild my rear end in my 2003 cobra.

            Don't forget

            Had a shop install bearings along with new ring and pinion gears. Ford performance parts make it a solid rebuild

            It's Ford Performance

            What can you say about a bearing and seal set, It is a quality set from Ford Performance so fit and longevity are not even in question. I installed new bearings with a new 3.90 gear set upgrade even though the originals only have 35,000 miles on them and still look like new....

            Love dealing with American muscle

            I got these bearings and seals and one of the bearings was not rolling free as it should. It set me a couple of days back but stuff happens. American muscle made it right and I will recommend them to anyone. Thanks guys!

            Rear axle bearing and seal kit

            You only need to order 1 quantity as this kit comes with two seals and two bearings. I made the mistake of ordering two and now have to send back the extra.... Otherwise great parts!

            They fit the INNER axle bearing, not the OUTER as described.

            Ronnie Gardner at PRIME TIME Racecars (5000 Summit Av in Greensboro, NC) installed the bearings and seals in my 8.8 when he installed the new 3.90 gears. I removed the differential and took it to him; I am currently putting the entire IRS back together. Ronnie spoke highly of Ford Racing. The only point I want to make is "Outer" means next to the wheel. "Inner" means next to (or inside) the Differential. These bearings are INNER axle shaft bearings - they are inside the Differential.

            Just what I needed!

            The bearing kit was exactly what I needed. They are high quality and are sold as a kit. Make sure to replace the seals as well. Don't skimp out on that process, or your rear may leak. This kit can be installed by the average guy, it only takes a little mechanical skill. If you don't feel confident about this kind of work, I would suggest taking them to your local machine shop to have pressed in.

            Great fit and cheap insurance

            Bearing and seals fit perfect in my extra rear end. Cheap insurance if you are doing a gear install. Absolutely a must if it has a decent amount of miles on it when you get in there. Nice to know that it's a Ford kit so you know it's reliable quality not a cheap knock off.

            Came in Ford Parts box

            Had them pressed in at machine shop for about $30, so far so good. No leaks from the seals. Pulling the IRS diff out is a tough job though!
