Using the Andersen Trailer Jack Blocks

California RV Specialists offers sales of all the Andersen 5th wheel and RV stabilization products. 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. Because the jack doesn’t need to extend fully, there’s less stress on it from movement. It’s a win-win.

Advantages of the Andersen Trailer Jack Blocks

  • Eliminates nearly all movement and sway in parked RVs and trailers (less stress on your trailer)
  • Double use for your money. Use them as a seat, a motorcycle stand, or a water bucket to put out your campfire!
  • Recessed pad area is 9-1/8″ diameter, recessed post-hole is 2-1/2″ diameter
  • Dimensions: 8″ tall, 12″ diameter at base, 10″ diameter at top (14″ tall when double-stacked)
  • 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.)

If used on motor homes you might raise the front tires off the ground. I still use my old Levell-Up ramps which work well.

We’ve used a stack of Lynx blocks (& a cap) for more than 10 years, under the elbow stabs on both our last popup and our current 17′ travel trailer. They are more stable if not cranked too far out, and having the blocks is better on the gravel, grass, dirt, etc. surfaces we often have in camp. We also use a stack under the tongue jack.
In a couple of places we go, they require pads under stabs on the asphalt surface, to prevent damage, since the asphalt can soften in hot weather.

I swore by these for my fifth wheel landing gear and replaced one i lost in the Yukon as soon as i got back to the States….until they broke. My fifth wheel isn’t that heavy compared to many. Don’t trust them anymore. I put snap pads on all 4 of my legs and will use wood if i need more height.

I use multiple 2 x 10’s. Why spend so much money for more plastic that eventually ends up in the oceans?

Pricey and bulky. Having trouble justifying for both reasons. I do like the idea of a magnet to hold in place while the jack is in the raised position.

My jacks’ blocks consist of 2 sets of 10 interlocking pads each. Each pad is approximately 1 inch thick. As many sites encountered are unlevel, once the trailer is positioned, I use a level with a laser set on the highest single pad placed under a jack to determine how many pads should go under each of my other 3 jacks. Once the stacks are level, I use the remaining pads to make best use of the pads and minimize all 4 of the jacks’ stroke.

We don’t have the need for the blocks, but we do have the Anderson levelers and absolutely love them. It is so easy to level our small trailer since we got them. 100% satisfied with this purchase.

We boondock at dog shows frequently which means in fields or dirt. I would assume we still need the pieces of wood we now use under our Snap Pads.
