Webb Wheel Products Inc has added two new aluminum hubs for R-series drive axles to its line of Platinum Series products. These hubs — part #4653 with 3/4" drive studs and part #4656 with 5/8" drive studs — each weigh 21 pounds and were designed for “short” R-series axle applications. Webb previously introduced aluminum hubs for TN and P series trailer axles. The firm says its hubs, combined with new Platinum drums, save up to 16 pounds per axle.
