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!

We took our 5er on the first trip this weekend since installing the stabilizers. I discovered one thing that should be mentioned concerning the operation.
I lowered the landing legs down to where the 5er was level and started to ratchet the bars to put pressure on them. One of them clicked one time and was very tight. The other one would not tighten enough to click. The leg was in just the position that would not allow the bar enough movement to ratchet. I lowered the landing legs just a tiny bit and that allowed me to ratchet it one click. Then I raised the landing legs just a small amount to put a little more pressure back on them. One caution here. I have stated earlier that you should not use use the landing legs to tighten the bars, but this is one time that it was necessary. You should apply VERY LITTLE pressure on the bars with the landing legs, or you could easily strip the ratchet assemblies!

I got a deal on a different type of cargo bar. The ones that are used on the insde for securing the slide-out.
(as seen here for $17)
I first moved my front jacks back about 20" and added the stabilizers going forward. Then I move my rear jack forward about 18" then added the stabilzers going up to the center of the trailer. The thing is rock solid and I dont even have the bal-X chocks between the tires when I tried it. I'm completly satisfied and all for under $120.00 including hardware. Thanks for the write-up and photos, it gave me the courage to do my own.

Yup, that's an option. I did the same, bought the ratcheting
bars, but, I don't have them permanently attached. And I don't
put them on the bottom of the front landing gear. It will move
the landing gear. I place my landing gear on 10x10 inch blocks.
Drive a large tent stake on the outer side of the 10x10 blocks to
keep them from moving and place one end of the bar on the top
of the front landing gear and the other end on the bottom of the
opposite block. No movement. Can't be beat!
For the rear scissor jacks, I use angle iron, top on one side,
to the bottom of the other side and clamp with C-clamps. Just
as steady as the 1000's of buckazoids pro jobbers, for real cheap!


I can't imagine the bars moving a landing leg with thousands of pounds weight on it! Also, what do you do when you're on a concrete slab? I think it would be easier just to spend a couple of hours installing them permanently. To each his own...:B

I think concrete blocks are the ultimate if you remove the wheels. This is actually the number one home improvement in Alabama.

Great job and nice post. I have been toying with the idea for a while now and it seems that the rachet setup would be far superior to the tightening eye bolt I was planning on using. I'm guessing when you get a chance to use them, you will be very happy.

Thanks Les! I don't have a clue how you would use these on a TT, but I bet you will figure it out! Good luck! :B

Ed, I can't quite picture what you describe. The stabilizers attach to the bottom of the jack and to the underside between the jacks. My RV had a metal bottom there because it was prepped for a generator. My friend's 5er that we did yesterday had 3/4" wood there. The upper ends attach under the floor of the front storage or generator compartments. My battery is in that compartment also.
There may be a crossmember that you could attach to if needed. The upper ends of the stabilizers can be attached several inches off the centerline between the two jacks. Hope this helps!
