The OTC Stinger Kit, No. 4408, includes an aluminum drive handle and six heavy-duty, composite bearing and seal drivers to fit most standard wheel bearings ranging from 1.555" to 3.189". The drivers have different diameters in order to match different-sized bearings, and three of the drivers are formed with two different diameters. Only weighing 2 lb. 4 oz., the 4408 kit is lightweight and packaged in a rugged blow-mold case for easy storage.
