Fitment & Compatibility
Only axles with a 4.84-inch center register match these rear rotor hats. Use the table below to identify the listed Silverado/Sierra 2500 and 2500HD, 3500 single-rear-wheel, Avalanche 2500 and Suburban/Yukon XL 2500 configurations. Retain the factory parking mechanism and verify the eight-lug hub before installation. DS-560 lists separate rear hoses 220-9811 for 1999–2006 and 220-18649 for 2007–2011; later listed applications require connection and routing confirmation. A 4.63-inch axle register needs a different kit. Nominal minimum wheel diameter: 20 in; 508 mm. Compare the actual wheel barrel and spokes with the linked clearance drawing; diameter alone does not establish fit.
