2001-2006 GMC Sierra 1500 (excluding 4 Wheel Steering) Rear Brake Backing Plate

Part Details

  • Location: Rear

This part replaces:

  • DORMAN 924-002
  • OE # 19178785, 19178786

  • New

This, rear disc brake braking plate, or brake dust shield or cover, is a new aftermarket part. It bolts to the rear end and serves many functions including holding brake parts in place and keeping dust and road debris away from the backside of the rotor. Over time, the backing plate will rust away or become damaged from years of weathering and brake jobs. Why not replace your damaged or rusted out disc brake backing plate now and help bring back the integrity of your brake system!

Specifications:

  • Fits either LH (Driver Side) or RH (Passenger Side)
  • Bolts to rear end
  • Made from stamped steel like originals, but coated with rust proof paint
  • Replaces dealer part numbers: 12472851, 12476287, 19178785, 19178786
  • Built to strict quality control standards
  • Will need to reuse original mounting hardware
  • Only fits vehicles that have rear disc brakes
  • Will not fit vehicles with rear drum brakes or with 4 wheel steering

Note: For 2007 truck models, the Classic Style has a crease down the center of the door skin where on the new body styles, the door skin is smooth. This part is for the Classic style truck.

This rear disc brake backing plate is a great replacement and has good cost savings over dealer unit.
