Put firmer stopping power behind your Ford F-250 or F-350 Super Duty with the Power Stop Z36 Truck & Tow Brake Upgrade Kit K5575-36, a disc brake upgrade for 4WD heavy-duty pickups. It is made to give these trucks a stronger braking setup than the factory equipment when a trailer is hitched or the bed is carrying a full load. The kit covers the 2010 to 2011 F-250 Super Duty 4WD and the 2010 to 2011 F-350 Super Duty 4WD with single rear wheels. Both 2010 applications depend on build date, with the F-250 listed for trucks manufactured from 2/12/2010 and the F-350 for trucks manufactured after 9/16/2010, so compare your truck with the fitment list below before ordering.
