We supply jack stands in four primary load ratings: 2-tonne (2,000 kg, 4400 lb), 2.5-tonne (2,500 kg, 5500 lb), 3-tonne (3,000 kg, 6600 lb) and 6-tonne (6,000 kg, 13200 lb). As a trusted B2B tool supplier, we emphasize that the rated capacity is the maximum allowable load per single stand. For maximum safety in a workshop environment, always use stands in pairs.
