Dace MFG Mugen Pillow Balls
Dace Manufacturing have released this set of 4 pillow balls for use with Mugen buggies and truggies. They are 2.5mm longer than stock allowing more threads to bite in the a-arm, those that run wider set-ups will really benefit from the longer threads. The ball ends are specially coated to make them incredibly durable and Dace offers a lifetime guarantee on these balls, replacing them if they come apart.
