Dealing with small differential balls during a rebuild is tedious and frustrating, but not anymore! The VSR Easy Ball Diff Builder fits all common 1/10 scale ball differential components 3/32" or smaller. It is designed to hold all of the diff balls in the main compartment, and then allows them to "pour" out the track in a single file line. We recommend tipping the Easy Ball Diff Builder over your greased diff gear, and tapping lightly on it to allow only one ball to exit at a time. So easy!
