The Power Stop Z36 Truck & Tow Brake Upgrade Kit is a disc brake upgrade for full-size GM trucks and SUVs that tow trailers or haul heavy loads. Pulling weight adds heat and strain 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 a long span of model years, from the 2007 new body style Silverado 1500 and Sierra 1500 through 2020 Suburban, Tahoe, Yukon, Yukon XL, and Cadillac Escalade and Escalade ESV models. Also included are Avalanche, Escalade EXT, Express Van 1500, Savana 1500, and Cadillac XTS (6 lug) applications for select years. Pickup and early SUV fitment depends on rear disc or rear drum brakes and, for some 2007 and 2008 models, on front caliper bracket casting numbers 351C/352C. Compare your vehicle's year, trim, and rear brake type with the fitment list below before ordering.
