Merrick Heavy Duty Upgrade Kit for Standard Car Dolly (8 Pcs) Capacity_70 Ton it's sold in pairs toThe big difference between the Standard and Heavy Duty Auto Dolly is in the caster type and size. Our Heavy Duty Auto Dolly Casters are larger in diameter and outfitted with three beefy sets of bearings: One on the swivel and two on the axle. All of this adds up to three advantages over standard casters: It takes less force to get things moving and keep them moving. The larger diameter wheels also handle expansion joints better than the smaller ones.
