Best leveling jacks/blocks

Use the stabilizer chocks between the tires, I use the BAL X chocks sometimes or the light weight camco yellow plastic ones work too. Also putting a couple blocks under the stabilizers help too, I put pressure treated 6"x4"x14" wood blocks under mine. Adding two stabilizer stands near the axles will take the spring bounce out.

Add another set of stabilizers near the axles.

I got the JT Strong Arm bars that bolt to the jack and the frame of the trailer. They really make a difference. I have the standard scissor jacks on all 4 corners and no matter how tight you made them they bounced.

Push on the corner of your rig when it's setup and just see how much it moves.. Push forward to back and it moves even more.

The bars really take that movement out of the whole rig. It's not 100%, but it's 100 times better than it was before!

Here are the rear ones. These have the side to side and front to back.


Here are the front. Just side to side.


You have to drill and find the best place for them for your application and have a good drill set and a 3/8 tap if you need one..

Wood blocks to lessen the leveler distance. My SIL has a fiver with 6 auto leveling legs. Near full extension they got wonky.

One thing you might try is tire chocks.. I mean the ones that fit very tightly between the tires, not those cheap plastic blocks on the ground
