Overview
The BD044-D is an aftermarket brake drum for compatible 10,000 lb GD trailer axle applications using 12.25" × 3.375" brakes. It is intended for the earlier axle configuration commonly found on 2009-and-older Dexter applications and compatible Lippert trailer axle systems where all dimensions and identifying details match.
R&P Service Insight
Heavy-duty trailer brake components can look similar while using different axle generations and hub configurations. Confirm the original component before disassembly whenever possible.
- Check the casting: Look for 9-44 cast into the existing drum.
- Confirm the brake size: The required brake configuration must measure 12.25" × 3.375".
- Check the oil cap: The earlier application commonly uses a 21-36 four-inch oil cap.
R&P Knowledge Hub
Compatibility: Intended for compatible pre-2009 10K GD trailer axle applications where the brake size, original drum casting and hub configuration match.
System Fit: Designed for 12-1/4" × 3-3/8" heavy-duty trailer brake systems associated with the listed application references.
Installation Notes: Inspect the hub, bearings, seals, oil cap, brake shoes and related hardware during service. Replace or reuse those parts only as appropriate for their condition and specifications.
Performance Insight: Correct drum dimensions are necessary for proper contact with the corresponding brake shoes. An incorrect axle generation or drum configuration may prevent proper assembly or brake operation.
Brand & Fitment Note
Selling Type: Aftermarket replacement component.
Application References: Dexter, Lippert, 8-288, BD044-H and 9-44 are included as compatibility and identification references.
What This Means: This listing is for an aftermarket brake drum and does not represent a guaranteed Dexter- or Lippert-branded component.
Before Ordering: Match the existing brake size, axle generation, drum casting, oil-cap size and complete hub configuration.
R&P Repair Insight
Do not select this brake drum from axle capacity alone. Earlier and later 10K axle configurations may require different components even when their general appearance is similar.
- Axle year: Confirm the axle is from the applicable pre-2009 configuration.
- Drum identification: Compare the casting numbers on the original drum with the listed references.
- Complete inspection: Examine the brake shoes and related components for wear, contamination or damage before returning the trailer to service.
