Bearings and Seals

This bearing and seal kit includes two inner wheel bearingstwo outer wheel bearings and two inner grease seals. This kit is enough for two brake rotors and is intended to be used with a new rotor installation as this kit does not include the bearing races or cups.

If your project willl be making use of used rotors, you will require new bearing races or cups.  Therefore you will need to purchase the bearing and seal kit # 910-31052 suggested below in place of kit # 910-31000.

Works with Mustang II/Pinto and Granada rotors using Mustang II/Pinto spindles only. It will not work for installing Mustang II/Pinto brake rotors on 1949-1954 Chevy spindles. Not for use with early Chevy spindle brake conversion kits.
