Rated 4 out of 5 by from Good product Good jacks; just shorter than we anticipated. Had to purchase additional risers for them to reach the bottom of our trailer.

Ultra Stacker Jacks set of 4. (6000 lbs weight capacity) Can I use them to support the trailer, and remove the weight off the jacks

Asked by: Mike4681
These stacker jacks are used to prevent a camper from rocking while living inside, but is not design for direct load bearing like a leveling jack would. So SKU#85164 will assist factory installed leveling jacks, but will not remove the weight from said leveling jacks.
