Best Rated Sway Bars

I have a 2017 Tiffin 34PA on a 26,000# chassis. I did the CHF in front and back and it helped a lot with swaying. I also added a steering stabilizer. Still in wind (not even that strong) or when semis go by the coach is still getting pushed around a lot. My questions is will it help to add additional sway bars in addition to the CHF. If it will help, what brand and type would you recommend and who to install them? I am open to any and all recommendations!!!

Thanks,
Wes

Adding another Stabilizer Bar (SB) to the rear has to help. There is no room to add another SB to the front but you could replace the front with a larger diameter SB. At least I have never heard of adding another in front but have had several have two on the rear.

I have never heard much of a concern or discussion about which brand SB is better. The steel used is a spring steel like leaf springs. They deform and return to the original shape. What is good to know is the diameter of your stock SB's and what you decide to add. That's what will make a big difference.

On the two rigs that had three SB's plus the CHF both front and rear nobody ever complained of having two much SWAY control. I have been told several times you can have to much sway control and it will make the ride harsher. Still waiting for posters who post about harshness because of to much sway control.

A friend asked me to drive his RV and he wanted me to show him how to do a grease job on it. We met in town and I drove it about 15 miles to our house. It was an 18,000 lb chassis and I thought it handled very well. When I crawled under it I noticed 2 SB's on the rear and a new one on the front. That's why it road so nicely. He asked me if I perform the front CHF so I did. He called me after he got home and was even more pleased by the added sway control with the CHF.

Go figure!!! He never said he felt the ride was to harsh just how nicely it road and handled.

a 1 3/4' loadmaster seems to be the most popular upgrade for the front sway bar on the F53 chassis. You can put a total of 3 sway bars on the rear (original, plus two upgrades). If you are getting "pushed" around by wind and big rigs, a rear trac-bar may be a better solution, if you have to piecemeal the fix.

High Desert is correct. To put it another way a Stabilizer Bar (SB) will assist in controlling sway which is the tilting of the top of the RV left and right. A Track Bar (TB) stops lateral movement. There will be slop in the leaf spring shackles and bushings. That translates into side to side or lateral frame movement. A TB ties the frame and RV body together reducing some of the lateral movement.

When the rear end of the RV is effected by wind gusts causing lateral movement the front wants to correct it by adjusting the steering wheel.

Improved shocks will also help with the sway by increasing the dampening effect.

Look at Hellwig. Theirs is also 1 3/4 inch and was quite a bit lower cost than Roadmaster and the longer U-Bolts were included, when I did mine. Best price when I did mine was https://www.sdtrucksprings.com/

If you want the double rear auxiliary bar setup do some digging at Hendersons https://www.hendersonslineup.com/supersteer-products

Both places have great service.

Thanks so much for your comments. I want to look into the Track bar idea. Thanks for the tip to look at Hellwig also. You have help answer some my questions. I think my next purchase will be a front SB. You mentioned shocks. I hear good thinks about the Koni FSD shocks. Will These types of shocks also help with sway?

Add a rear track bar. The chassis doesn't have one. It needs one. Imho.

Do they make one big enough for a 26,000# chassis?

AK,

If your RV hits a bump and it compresses the springs it also compresses the shocks. Shocks are there to dampen the oscillations of the leaf springs which is basically a way of saying they dampen the springs movements. So absolutely the shocks will also help with sway which is also compression of the springs.

Unfortunately the shock industry (for RV's) does not make custom shocks based on a chassis weight. Bilstein lists the same shock number for all F-53 chassis from 16,000 to 26,000 lb. Koni's may also be the same. This has been mentioned often before but folks just don't seem to realize what is being asked of one shock to handle that spread of a weight.

AK you already have a front SB and a front TB. Yes you can change to a larger front SB but try things in the rear first and you may not need more sway control for the front. The Koni shocks seem to do a much better job as most have reported. They are not cheap at $180 each.

I was really impressed when adding a shock spring steering dampener which will cost you about $400. The shock dampens sudden steering wheel (SW) movement from wind gusts and the spring keeps the SW centered.

I talked with Roadmaster at length about sway bars, AFTER I did the CHF and added the heaver front Hellwig bar, as I wasn't happy with the results.

He said "You should have done he rear first, that is where the weight is." Hellwig said the same thing.

Across the manufactures it appears to me that the only difference in sway bars and trac bars is the mounting hardware and the color of the paint. IMO go with the one that saves you the most green.

I used the trac bar from Brazel's https://www.brazelsrv.com/UTF53V10R-...facturer_id=13 at the time it saved the most green. I see it is OOS right now but I would call.

Thanks for everyone's comments. It sure helps to have such a pool of knowledge to tap into. Ok after reading everyone's comments so far and doing some more research. I think I will now purchase a track bar for the rear (UTF53V1024R - Rear Ultratrac Trac Bar Ford F53 24-26k GVW Chassis). I will try this for our next trip. If that proves useful I think the next step will be some Koni shocks. I think the RV drives pretty good considering it is setting on a big truck chassis. I did make the mistake of driving my friend's DP and liked it. But that is a whole different animal that cost $100sK more. I am still open to ideas and like to hear everyone's thoughts

As an FYI: I have a 2020 Newmar Canyon Star 3710 on a 26,000 GVW F-53 chassis. I made the following additions with fantastic results!
1) Saf-T-Plus steering stabilizer
2) Ultra-Trac rear trac bar
3) Koni shocks front & rear
4) Sumo front springs

These additions made a big difference in ride, handling, sway, wind movement all.
I had them all installed at once, but only after a significant test drive of the new Coach. And having installed the Saf-T-Plus & Ultra-Trac trac bar on another coach I had previously owned. It was a Workhorse W-22 chassis, & these made a huge difference!

Liquid-Springs installation makes a HUGE difference in the ride & handling, but at about $12,000 cost; I'm still trying to decide if the difference is worth the money. Am leaning towards, YES, it i worth the difference. Especially the 3 position adjustability to handle differing road conditions! It was impressive!

Good Luck! Hope this may have helped you!

Jabber Jaw,
Thanks for your feedback. I had the Save-T-Pus installed when I first bought the RV. I did the CHF front and back which helped with the sway a lot. I see you did not mention any sway bar upgrades. Is there a reason for this or did you just not think it needed it? I plan to install a trac bar on the rear next and then the Koni shocks.

My coach is a 2020 model, & has the larger front sway bar. Not sure if the rear is larger or not.
And I did not do the "CHF", based on the recommendation of the Ford Dealer which did the other installations for me. And after driving my coach with the changes, I do not believe the "CHF" would further improve the ride. The Ford Dealer's Service Manager told me that in fact, the "CHF" could stiffen the ride, not help it. This Ford Dealer is the Ford Dealer which services all of Newmar's F-53 gas chassis' when they receive them from Ford Motor Co.
They do service work on lots of F-53's for customers, & some for Newmar as well. Very knowledgeable, helpful, & friendly! Bremen Ford; Bremen Indiana; about 8 miles from Newmar.

Thr "trac" bar will make a big improvement.! And you will be very pleased after installing the Koni shocks!

Lastly, with the way my coach rides, drives, & handles; I do not plan to do the "CHF" at this time.

Just wish I'd go ahead & pull the trigger to get Liquid Springs installed, but cannot yet bring myself to spend that amount of money!

Best of Luck, enjoy your coach!
