This bearing and seal kit includes two inner wheel bearings, two 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.

Overall Assessment

Customers highly recommend our product for its great quality, fit, and price. They report that the bearings and seals are of decent quality and perfect fit for their diverse range of cars and projects. Customers also commend the product's practicality as a complete package, save for a few missing elements like an outside washer or dust covers. Despite these minor setbacks, customers find that our product offers good value, eliminating the need to look up different items at different stores. Many found this product well made, easy to install and intend to buy again in the future. However, a few customers pointed out the offshore production, but overall satisfaction did not seem to be largely affected by this aspect.

Mustang II Rotor Bearings and Seals

The bearings and seals were well packaged. They appear to be decent quality. The car is still in the building stage so it will be a while to see the longevity after they've put to use.

Bearings were right, fit well. The seals did not fit granada rotors. This was the only reason i bought this kit was for the seals. Bummer.

Bought 2 rotors and decided to add the bearings. Better safe than sorry when driving a hand-built car.

What kit do I get for a 10" hybrid rotor on mustang 2 spindle that comes with races? The website says 910-31052, but I asked a previous question and was told that 910-31052 will not work with hybrid rotors. I asked the question under 910-31052.
