The Webb 16.50" x 5.00" Balanced Brake Drum (OTR_F25B) is a premium heavy-duty replacement part designed to deliver exceptional stopping power, durability, and reliability for commercial trucks, trailers, and buses. Built by Webb Wheel Products, an industry leader with over 70 years of wheel-end engineering expertise, this outboard-mounted brake drum features a 16.5-inch diameter and a 5-inch brake shoe width to handle intense friction and high load demands. Machine-balanced to industry standards, it virtually eliminates wheel-end vibration to foster smoother braking performance, cut driver fatigue, and reduce stress on adjacent hub components. Its high-grade cast iron design incorporates advanced venting technology to efficiently dissipate high temperatures during heavy braking cycles, preventing thermal warping, brake fade, and premature lining wear. Engineered for precision fitment and long-term durability, the Webb OTR_F25B ensures strict compliance with rigorous safety standards while keeping maintenance costs and downtime to a minimum.
