If you are in the process of regenerating your engine mount, these spacer sleeves tend to break away when you separate the engine shoes from the rubber mounts. Unfortunately, the spacer sleeves are only made of plastic.
You need 2 spacer sleeves per vehicle. You can install them if you have an MZ ETZ125, ETZ150, ETZ250, ETZ251, ETZ301, ES175/2, ES250/2, TS250 or TS250/1. We recommend that you always change these when you rebuild the engine mount.
