Keep the drum brakes on your medium-duty truck running true with the Dynamic Friction True Balanced Brake Drum (P/N 365-47072). It installs as a direct-fit replacement for the 1995-2009 Chevrolet W3500 Tiltmaster, 1987-1997 Chevrolet W4500 Tiltmaster, 1995-2008 GMC W3500 Forward, 1992-1997 GMC W4500 Forward, 1987-2009 and 2011-2018 Isuzu NPR, and 2012-2015 Isuzu Reach, and is cataloged for both the front and rear positions. See the Buyer's Guide tab for the full engine-level fitment.
The brake drum rotates with the wheel while the brake shoes press outward against its inner friction surface to slow the vehicle, so a worn, deeply scored, cracked, or out-of-round drum can cause pulsation, noise, or reduced braking. It arrives new in the box, ready to install with no modifications required, and is quality tested for long-lasting performance.
What vehicles does the 365-47072 brake drum fit?
It fits applications including the 1995-2009 Chevrolet W3500 Tiltmaster, 1987-2009 and 2011-2018 Isuzu NPR, and 2012-2015 Isuzu Reach. See the Buyer's Guide tab for the full list.
Does this brake drum come coated for corrosion protection?
Yes. It has a black high-temperature coating applied for corrosion protection.
Is it a direct-fit replacement?
Yes. It is designed to meet the same form, fit, and function as OEM brake drums and is machined to tight tolerances for a proper direct fitment with no modifications required.
How do I know my brake drum needs replacing?
Signs may include deep scoring, cracks, an out-of-round surface causing pedal pulsation, or noise. Have the drum measured and diagnosed to confirm the cause before replacing it.
Should I replace both drums on the same axle?
It is best practice to replace both drums on an axle as a matched set for even, balanced braking, though it is not strictly required.
