    bearing sizes

    I have a the traxxas mustang boss 302 vxl edition and ordered the bearing kit for vxl slash/rally and received the top bearing in the picture. the bottom bearing is the one I pulled off the car. so what bearing did I receive and what bearing do I need to get the car going again?

    You need a caliper to check the sizes.

    The extended views and part lists give the specifications of all the bearings in the car.

    got the car used and it didn't come with a manual. also I'm not driving 2 hours and wasting $20 to find out 2 bearing sizes. according to RCmart the top bearing should be a 4x7x2.5mm. so would the bottom bearing be a 4x8x3mm size?

    Inner carrier bearings are 8x12x3.5mm. Part number 7020.
    Outer carrier bearings are 4x8x3mm. Part number 7019.
    Are those what you are trying to show?

    You can use the MERV pages for reference of most mechanical parts.

    Well said, ksb.

    Since I was prepared that Traxxas some day would stop making the Boss, you can find the exploded views here.

    And if you want to stay home and still want a caliper for less than $20: click here
