STABILIZE YOUR CARAVAN OR MOTORHOME! The Andersen 'Trailer Jack Block' eliminates nearly all the movement in your parked RV or Trailer! You will be amazed how solid everything is when using the Trailer Jack Block with your stabilizer jacks! 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.


LESS STRESS! 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 (and your pocket book)!


With our new version you have built-in magnets so you can simply attach each Trailer Jack Block to the bottom of your stabilizer and hit auto-level - no need to check and adjust each block! Super-fast and super-convenient!


The Trailer Jack Block is extremely strong and durable -and resists dirt and oil. The blocks are stackable for extra height and can even double as seats or step-stools (Note: do not stack more than two high).

Product was as described and arrived ahead of schedule. The whole transaction was easy and seamless.

Wish I had two vans so I could justify two of thes

Love our Jack Big Block!! Doesn’t move when hitching/unhitching the van from the vehicle, base grips well into wet or dry uneven ground, even the sandy Simpson desert! No more stacking multiple bits of wood to get the right height, or playing with multiple Lego-like stacking blocks (that are slipperier than that good mate who stole your girlfriend in high school)! Gold (actually, it’s Red) - so is also hard to leave behind when you’re packing up camp… unlike the kids after a week in the Simpson!! “Do ya self a favour!”

Perfect for ZoneRV caravans with electric jockey j

Awesome product built solidly. Lifts the jockey jack plate up about 250mm which means less winding up or down. Handy for those with higher than normal drawbars for offroad built vans. Super strong and lightweight. Great product.

The Trailer Jack Big Block is lightweight, strong and stable. It's the perfect solution to the problem of our jack sliding off a stack of timber off-cuts, especially on sloping ground. We are very happy with our purchase.
