The ultimate 5th wheel stabilizers!

I believe I have discovered the ultimate home-made 5er stabilizers! I was at a Love's Travel Center and found the S-Line SL125-HT Ratcheting Cargo Bars at $19.95 each. The bar expands from 40 to 70 inches. It is very easy to convert to RV stabilizers as you will see in the pics below. Aside from the easy installation, the big advantage of these is the ability to use the ratchet to get the maximum pressure after the jacks are in place, thus making the 5er more stable. When you're ready to pull out, you simply move the ratchet to the free-moving position, releasing the pressure, and raise the jacks! See what you think.

This is what the bars look like before modification



The first step is to use a wheel grinder to grind off the head of the rivet which is securing the foot on the large end opposite the ratchet. Drill out the hole where the rivet was to 1/4 inch. One caution here, on one of my bars the rivet hole was too close to the end of the bar so I had to drill a new hole 90 degrees over. I had to use a small drill press to drill the holes in the bar as a hand drill kept grabbing as the bit went through. Below is what you have now.




Now you will need to drill two 1/4 inch holes in the foot at the other end of the bar to mount it to the landing jack. Check the hole spacing on your landing jacks to determine the spacing of these holes in the foot. The holes in my jacks were 1 inch apart, but I don't know if that's a standard. Next you make the brackets to secure the bars to the underside of the 5er. You have a choice here. You can leave the bars full length and use two brackets, crossing the bars in the middle, or you can use one bracket and cut off the bars to fit your 5er. I didn't have the shop facilities to properly cut off the bars so I took the simple way and used two brackets.
I made the brackets from a piece of U-shaped steel bracket. It should be at least 1 1/2 inches inside, as the bar is 1 inch in diameter. CAUTION..when you drill the hole through the sides for the bolt that goes through the bar, be SURE to measure from the SAME end of the bracket to mark the holes in the two sides! I learned this the hard way! Use a 1/4 inch hex head bolt with locking nut to secure the bracket to the end of the bar.Below are the finished brackets and the bracket attached to the bar.





Next, you want to determine the correct position for the mounting brackets on the underside of the 5er. First, release the ratchet on the bar and slide it to it's shortest length. Then, place the remaining foot on the bar all the way up against the inside of the landing jack, and secure temporarily with cable ties, tape, etc. You need to determine a center line between the two jacks. Measure from the inside center of one jack to a reference point towards either the front or back of the 5er. This could be the front edge below the storage doors, a cross member underneath, etc. Raise the end of the bar with the bracket up to see about where it will touch the bottom, then at that point make a mark on the bottom at the measured distance. In other words, this mark should be on a center line between the two jacks. Now, measure 1 inch from the center line forward or backward and make another mark. This will be the inside edge of the mounting bracket. One bracket should be 1 inch FORWARD of the center line, and the other bracket should be 1 inch BACKWARD from the center line. This is to give the two bars some separation where they cross in the middle as they move up and down. You may have a situation where there is nothing to mount the brackets to directly between the two landing jacks. These mounting brackets DO NOT have to be directly in line with the jacks! You can move several inches forward or backward to find a suitable surface without affecting performance. Just be sure to move both brackets forward or backward! Go ahead and bolt the brackets to the bottom. Now, remove the foot of the bar from it's temporary mounting at the top of the jack. With the ratchet in it's free moving position, move the foot down to the bottom of the jack and use the 1/4 inch hex bolts to secure the foot in the lowest possible position on the jack. The ratchet can be rotated to whatever position you prefer by a small clamp using a #2 phillips screwdriver and a 8mm socket. YOU'RE DONE! You'll leave the ratchet in the free-moving position while you lower the jacks to level the 5er. When it's level, move the ratchet handle to the center position and apply pressure. You'll find that you will probably only get one "click" of the ratchet but that's enough. The handle can now be folded to the closed position. There is a small bar under the handle that has to be pulled to move the handle through the different positions. One last and very important suggestion...print a warning label in LARGE letters and place it near your switches that control the landing jacks. If you forget to release the stabilizer ratchet before you start raising the jacks, IT AIN'T GONNA BE PRETTY! Good luck!

P.S. Adding this statement because of what someone said about the normal operation of JT stabilizers. DO NOT USE THE LANDING JACKS TO PUT PRESSURE ON THE STABILIZERS!! Lower the jacks to the position where the 5er is level, use the ratchet to put pressure on the stabilizers, and LEAVE THEM LIKE THAT! Using the jacks to put the pressure on the stabilizers might very well strip out the ratchet mechanism!

Also cn be made for a support for the slide outs and they do work great for the cost. ($30.00 at harbor freight when they are there). can use the screw type as well

I admire your dedication and resourcefulness - but I must comment:

I have JTs, and I have your stabilizer that I use to secure loads in the back of the truck. Your stabilizer is just not strong enough for the purpose you've adapted it too. I can flex mine by hand just spanning the bed of the truck. The ratchet also cannot exert enough pressure and would not be able to hold the pressure of the landing gear when trying to "set" the stabilizer like the JTs. Lastly, the ratchet only works against compression, not extension. The JT set screw works to secure both ways, which is part if the success.

To be honest, I bought one of your stabilizer at the same time as another brand that actually has opposing threads on each end that lets you turn the shaft to secure it between the bed and I prefer it over the ratchet type.


You may prove me wrong, but I don't see where they would not be strong enough. As for the flexing, they will never be extended but a few inches and I challenge anybody to bend one of them in that position. I'm not that familar with the JT's but I assume that you would bring the jacks down to where the trailer is level, go a little bit more, lock the JT's in place, then raise the jacks back to the level position, thus putting the pressure on the JT's. Correct me it that is not the correct way of setting them. With these stabilizers you just put the jacks down to the correct position, ratchet the stabilizer to put the pressure on, and you're done. Anyway, glad you're happy with your JT's and I really believe I will be just as happy with mine, for a WHOLE LOT less money! :B

I bought a set and use them in the same way only I just store them in the cargo area when we travel. Wonder if I can do the same with the rear jacks too. I have BAL jacks and they aren't impressing me at a all. Once I set them in place and take away the crank handle, they will turn backwards or unscrew making them ineffective. Also has lots of side to side movement in them that I think these bars may help with.

I don't know, yet.
I think you should make a second set and try them on my fiver.
Nice job and well done.

They may not be as effective as the real thing (JT's) However they did not cost nearly as much. I'm sure they have a dramatic effect vs. nothing at all.
I'll take 70% effectiveness for 20% of the cost.
Great Idea, thanks for sharing.

Hey for $50-60....great idea/project!! I like your resourcefulness :B

DO they work......I bet they do. So that makes it worth while.
Been thinking about a set of 'home-mades' myself.

Thanks for the pic's.
Is it time for your medication or mine?
