Brake Drum 3922X / 85123788002 - 16.5" x 7" Rear Axle for Fruehauf and Strick Trailers

A trailer brake drum spends most of its life doing nothing in particular, and then for forty seconds at a stretch it absorbs the entire kinetic budget of an eighty-thousand-pound combination. That cycle, repeated thousands of times, is what the drum is engineered for. The 3922X is the 16.5 by 7 inch cast-iron drum spec'd for the rear axles of Fruehauf and Strick trailers, two of the most common North American van and refrigerated trailer manufacturers in the line-haul fleet. Heat dissipation, hoop strength, and friction-mate compatibility are all set by the casting profile and the wall thickness, and the 3922X holds those tolerances against the same standard the OEM drum did.
