The Walthers Proto 920-2301 HO Scale 33" Metal Wheelsets with Plastic Axles, pkg(12), are upgrade components for HO scale rolling stock. The 33" diameter is correct for freight cars, and this pack provides enough to upgrade six standard freight cars. Metal wheel treads improve rolling performance over all-plastic wheelsets while plastic axles keep per-car cost low. Replacing plastic wheelsets delivers better rolling performance, improved electrical contact, and more realistic appearance. NMRA-compliant profiles ensure reliable tracking on any HO layout. Drop-in fit for most standard HO truck frames.
