Detailed Product Description

What This Brake Drum Helps Address

  • Rear brake pulsation caused by a worn or out-of-round drum
  • Reduced braking consistency from heat-worn drum surfaces
  • Brake shoe contact issues from incorrect drum dimensions
  • Service replacement needs on aging Dodge rear drum brake systems
  • Fitment problems when the original drum no longer meets specification

Installation Notes and Tips

Verify the vehicle’s rear brake configuration before ordering, including the 12 in x 2-1/2 in drum brake setup and the listed overall height requirement where noted. Confirm the 8-lug wheel pattern and compare the existing drum dimensions to the 13.850 in outside diameter and 3.100 in depth before installation. Clean the hub mounting surface and inspect brake shoes, wheel cylinders, and hardware condition during service so the new drum can seat properly.

Quality Assurance

Raybestos is a long-established brake parts brand, and the R-Line is positioned as a replacement line for routine brake service. The 8102R brake drum is built to the listed dimensional specifications for the confirmed Dodge rear applications.
