Product Details

DuraGo BD8923-01 is a coated rear brake drum designed around the specifications used on many Ford Ranger and Mazda rear drum brake systems. The titanium gray finish adds corrosion defense to the drum exterior, while the coated hat and edge help reduce rust buildup in exposed areas. With a 10-inch nominal drum diameter, 5-bolt pattern, and 4.5-inch bolt circle, this drum is built for direct service replacement where the original brake drum matches these dimensions.

This part cross-references Ford OE numbers 1F8026251 and 6L5Z1126A for the same application.

What It Helps Address

• Brake pulsation or uneven rear braking caused by worn drum surfaces
• Rust buildup on the drum exterior and hat area
• Reduced braking consistency from an out-of-spec drum diameter
• Noise or vibration related to drum wear or corrosion
• Service replacement needs on rear drum brake systems for Ford Ranger and Mazda B-Series vehicles

This drum is listed for rear position applications only, including 1998-2009 Ford Ranger rear, 2001-2009 Mazda B2300 rear, 1998-2009 Mazda B4000 rear, 1998-2007 Mazda B3000 rear, 1998-2001 Mazda B2500 rear, 1991-1994 Ford Explorer rear, 1991-1994 Mazda Navajo rear, 1980-1983 Ford F-100 rear, and 1980-1983 Ford F-150 rear.
