Stehl uses E/Z Lube Hubs, eliminating the need for disassembly of the wheel bearing for repacking. Our fenders are steel with 3 steel support braces. Stehl uses a factory molded, plug together wiring harness. Stehl uses a powder-coated paint that is the most durable finish on the market. This paint is second to none and keeps your dolly looking good long after you buy it.
