OTR 16.5" x 7" Balanced Outboard Mount Brake Drum by OTR is a heavyduty replacement drum engineered for commercial truck wheel ends that require outboard mounting and a 16.5" x 7" service envelope. Designed to address common wheelend failure modes, this brake drum restores correct mating geometry between the brake shoes and the drum surface to deliver consistent braking torque and repeatable stopping performance. The balanced construction reduces wheelend vibration that accelerates lining and bearing wear, helping to extend component life and maintain predictable stopping distances across duty cycles. Because the drum conforms to the dimensional profile for 16.5" x 7" systems, it enables straightforward installation during scheduled maintenance or corrective service, minimizing shop labor time by eliminating the need for fitment modifications. The robust outboard mounting design supports even heat distribution across the braking surface, which helps control thermal distortion during repeated highload stops and reduces the frequency of drum resurfacing or replacement. For fleet operations, consistent drum geometry and balance translate into measurable operational value: more time between brake overhauls, reduced unscheduled roadside stops for wheelend issues, and steadier brake performance under load. The product is intended for fleets and service shops that require durable, serviceable replacement drums that integrate into standard 16.5" x 7" outboard brake systems. Installers should follow vehicle and axle manufacturer procedures for torque, bearing preload, and any wheelend adjustments to ensure safe operation.
