Built around a short list of late-model GM trucks and SUVs, the Power Stop Z36 Truck & Tow Brake Upgrade Kit K2067-36 is a disc brake upgrade for vehicles. Towing and hauling add extra weight and heat to every stop, and this Z36 Truck & Tow kit is made to give these vehicles a stronger braking setup than the factory equipment. It covers 2005 to 2007 Chevrolet Silverado 1500 and GMC Sierra 1500 (6 lug) pickups with rear drum brakes, along with Sierra Denali and Silverado SS models, and the 2007 Chevrolet Suburban 1500, Tahoe, Avalanche, GMC Yukon, Yukon Denali, Yukon XL 1500, and Cadillac Escalade, Escalade ESV, and Escalade EXT. For 2008, it fits the Escalade, Escalade ESV, Escalade EXT, and Avalanche with front caliper bracket cast number 285/286C. Because fitment depends on rear brake type, trim, and caliper bracket casting, compare your vehicle with the fitment list below before ordering.
