What to know before buying
Listing details to confirm
The listing is contradictory on capacity: specifications say 10000 Pounds, while feature text claims G.V.W 40000 Lbs per block. It also alternates between 11.6-inch dimensions and about 11.5 inches, and claims a 4-piece set in the title while the contents field only names a Trailer Jack Block. Confirm the applicable load rating and selected set contents before buying or loading. These are listing inconsistencies, not established product defects.
