Trailer Jack Block

Fast & Easy Trailer Stabilization

Using the Trailer Jack block under your jack(s) means your jack doesn’t need to extend down as far, saving on wear and tear over time. And because the jack doesn’t need to extend fully, there’s less stress on it from movement - it’s a win-win for RVs and Trailers.

• Built-in magnets instantly attach to the jack, so there is no need to double-check and adjust each jack block.

• A 2-1/2” recessed post hole works great with post jacks

• Stackable for extra height (no more than 2)
