Semi Truck Brake Drums
Drums by the three numbers that decide fit: drum size (15x4, 16.5x5, 16.5x7, 18x7), bolt pattern (10 bolt on 11.25 inch) and mount (outboard or inboard). We stock the common heavy-duty interchanges — 3922X, 3807X, 3600AX, 3800X, 3598X, 3758X — balanced from the factory. A 16.5x7 drum weighs about 109 lb apiece, so a pair moves by freight and the shipping quote reflects it.
