You can order the standard shoe assembly or the heavy duty shoe assembly. Both use the 1" spindle and are preloaded with washers and include the linch pin. To give you an idea of difference in the shoe assemblies the standard shoe assembly weighs approx. 9 pounds and the heavy duty shoe assembly weighs approx. 12 pounds. Our aftermarket shoe assemblies replace the manufacturer number 49067 and 49071. But if you just need extra washers, the 1-1/2" spacer washer or extra linch pins we've got that too.
