        An unnecessary purchase for me

        Even tho I have a 2010, it was built in 2009 so this was not needed when installing new 3.73 gears inn my rearend. As always, AM customer service was great responding to the return.

        More Punch

        The 355 gears are a great middle ground choice you get more out of the hole and a lot more snap at speed when put the hammer down with out losing your cursing ability Love it ! Richard

        Nearly forgot them!

        You MUST purchase this bearing when changing your gears! The old one will get damaged if you remove it from the old pinion. I nearly forgot to purchase this, But while talking to an AM CS agent he reminded me to buy this... He was right, My mechanic asked me if I had it as soon as I told him I was there for a gear change! Saved me from having any delays!! :)

        needed for gear change

        any time you swap gears or if your building the rear in your car you'll need to buy a new pinion bearing.

      Does this bearing come with the race also?

      • The Ford Rear Gear Pinion Bearing - 8.8 in. contains only the rear gear pinion bearing.

      If the bearing doesn't come with a race, where can I get one? Or will the C L rear gear pinion bearing fit and work will with the ford performance high torque install and bearing kit?

      • The Ford Rear Gear Pinion Bearing - 8.8 in. is required for installation for the 2010 + 8.8" gear installation. It is also a good idea to install the Motive Rear End Installation and Bearing Kit - 8.8 in., item # 21201, ( when changing out the gears as well. You will not need another race or more bearings if you get this kit.

      helo is this included in the installation kit ?

      • Unfortunately, the installation kit for the gears will not include this bearing. This would need to be purchased separately from the kit if you have a 2010 and newer Mustang.
