The Bosch Blue Disc Brake Pads feature OE-style, multi-layer shims that provide noise dampening characteristics. The Blue Disc Brake Pads come towel-wrapped on select applications for added protection and value. The material used is similar to the shop towels that technicians use on a daily basis when working on vehicles. The brake pads are now available for some 2012-2013 Freightliner Sprinter 3500 and 2011-2015 Mercedes-Benz Sprinter 3500 units. One kit includes hardware.
