Product Details

The Dynamic Friction Company 365-80004 True Balanced Brake Drum is a direct-fit OEM-quality replacement drum engineered for reliable, vibration-free stopping performance. Cast from premium G3000/G11H18 gray iron, this drum delivers the strength, stability, and heat dissipation required for consistent braking under demanding conditions.

Key Features:

  • Premium G3000/G11H18 Iron Casting — Superior metallurgy ensures long-lasting durability and consistent friction surface performance
  • True Electronic Balancing — Machined and balanced on dedicated vertical turning centers and balancing machines, not shared rotor lines, for precise drum-specific tolerancing
  • Smooth, Vibration-Free Braking — Each drum is electronically balanced to eliminate vibration and pedal pulsation from the very first stop
  • OEM Direct Fitment — Built to O.E.M. specifications; no modifications required for installation
  • High-Temperature Corrosion Coating — Black high-temperature coating protects against rust and corrosion
  • 100% Quality Inspection — Every drum passes a full inspection station verifying critical attributes for proper form, fit, and function
  • 1-Year Warranty — Backed by a manufacturer's warranty covering defects in materials and workmanship

Sold individually, the DFC 365-80004 brake drum is new in box and ready to install right out of the packaging — no resurfacing or break-in machining needed.

Shopping took longer than I thought

19 August - So far, so good - Awaiting delivery...

Great prices and a surprisingly fast delivery, which despite choosing the most economic choice (2-14 days), I received the items in 5 days - saved more than half in shipping. Great all around experience and great product extremely well packaged. Thank you, folks!

Great so far
