This is a pack of two (2) Jack Blocks

NEW VERSION NOW HAS BUILT-IN MAGNETS! Faster and more convenient then ever!  Magnets Click to your RV's jack pads for perfect alignment every time! 

Stabilize your RV or trailer with the Trailer Jack Block. The 8" raised platform eliminates nearly all of the movement in your parked RV or trailer by providing a strong sturdy base that won't wobble like your landing gear legs. 

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 RV's and Trailers (and your pocket book)!

You will be amazed how solid everything is when using these blocks!


  • The Trailer Jack Block is extremely strong and durable - 6000 lb rating (single block) and 1,500 lbs (double-stack)
  • Dimensions: 8" tall, 12" dia. base, 10" dia. top (14" tall when double-stacked)
  • Recessed pad area is 9-1/8" diameter, recessed post-hole is 2-1/2" diameter
  • Resists dirt and oil
  • Each block weighs 5.3 lbs
  • 3-yr Limited Warranty

For great results, use two blocks at the front and two blocks at the back of your RV. If you want the most solid and absolute best results on a trailer that has more than 4 stabilizer jacks, use one block per stabilizer. Blocks are sold individually.

When you aren't using the Jack Block for stabilizing your trailer, it works great as a step stool or as an extra seat around the campfire! They are also stackable for easy storage. (Note: do not stack more than two high).

The Trailer Jack Block from Andersen Hitches is 100% made in the USA –it's built tough and built to last!
