Can I use this for engine removal work?

Yes — the adjustable height and sturdy base make it solid for supporting engines and transmissions during removal and install. Always use multiple stands and verify stability before placing weight on top.

Will this work on uneven shop floors?

Best results come from flat, level surfaces. If your floor has minor slopes, test the stand's balance before loading it. Rubber feet help grip concrete, but a level spot is always safer.

How do I lock the height adjustment in place?

Mounting method and locking mechanism not specified — test-fit your desired height before committing to work, and verify the stand holds firm under load before placing parts on top.
