OTR 16.5" x 7" Balanced Outboard Mount Brake Drum is engineered for heavy-duty fleet wheel ends where consistent stopping performance and predictable service intervals are critical. This outboard-mount design positions the drum for precise alignment with brake shoes and backing plates, reducing the need for repeated adjustments and lowering wheel-end downtime. The drum is machine-balanced during manufacturing to minimize vibration and brake chatter that can accelerate wear on shoes, bearings, and hub components. A machined braking surface provides consistent shoe-to-drum contact for repeatable stopping force and optimized shoe life. Increased thermal mass and an engineered shape promote heat dissipation during sustained or repeated braking events, helping to reduce brake fade and maintain braking torque under heavy loads. Precision machining of the pilot and mounting interfaces supports reliable fit-up at installation and preserves wheel-end geometry that fleets depend on for predictable maintenance planning. Where applicable, published specifications note a 7.00" brake shoe width and an approximately 8.78" pilot diameter, dimensions that contribute to interchangeability with common heavy-truck wheel-end configurations. By addressing vibration, heat management, and fit accuracy, this brake drum delivers measurable operational value: extended brake component life, reduced frequency of unscheduled shop visits, and more consistent braking performance across long hauls and vocational cycles. The drum is produced to industry machining and balancing practices and is suitable for use in a wide range of commercial truck and trailer applications that require an outboard-mounted 16.5" x 7" solution.
