July 2020 Update:
Harbor Freight added a fourth jack stand to their recall list. This jack stand has been recalled because of the weld splitting (breaking). This new recall is for the Pittsburgh 3 ton jack stand number 56373.

The May 2020 recall applies to three-ton and six-ton heavy-duty steel jack stands with these 3 item numbers:
56371
61196
61197
The number on the three-ton units can be found on the label at the top while the six-ton stands have their numbers printed in the yellow section of the label found on the base. These jack stands carry the Pittsburgh Automotive brand name. These jack stands have the potential to disengage their support pawl under shifting weight, causing the stand to drop suddenly. Based on the NHTSA filing, the recall applies to approximately 454,000 jack stands made between 2013 and 2020.

Harbor Freight urges anybody in possession of affected jack stands to return them to a store in exchange for a gift card equal to the current shelf price of comparable models. Any unsold jack stands covered by the recall have been removed from stores. Owners may contact Harbor Freight customer service at (800) 444-3353 or email: recall@harborfreight.com
