Big SUVs and full-size trucks that haul trailers and heavy cargo ask a lot of their brakes, and the Power Stop Z36 Truck & Tow Brake Upgrade Kit K2015-36 is a disc brake made to upgrade. This kit is matched to 2000 to 2006 Chevrolet, GMC, and Cadillac applications that use dual piston rear calipers, limited slip axles, or 4WD drivetrains. Covered models include the Silverado 1500 and Sierra 1500 (6 lug), Silverado SS, Suburban 1500, Tahoe, Avalanche 1500, Yukon, Yukon Denali, Yukon XL 1500, and the Cadillac Escalade, Escalade ESV, and Escalade EXT. Later model years (2003 to 2006) are mostly 4WD SUVs, while the pickups carry dual piston rear calipers with or without QuadraSteer.
