Bring added stopping power to your Chevrolet Silverado HD or GMC Sierra HD with the Power Stop Z36 Truck & Tow Brake Upgrade Kit K6259-36, a disc brake upgrade for heavy-duty pickups that tow, haul, or go off-road. It is made to give these trucks a stronger braking setup than the factory equipment when a trailer is hitched or the bed is loaded. The kit covers the 2012 to 2014 Silverado 2500 HD and Sierra 2500 HD, plus the 2012 to 2019 Silverado 3500 HD and Sierra 3500 HD in single rear wheel configuration only. Your list shows no 2500 HD trucks after 2014 and no dual rear wheel trucks, compare your truck's year with the fitment list below before ordering.
