Suspension upgrades

Purchased my 2016 ACE 29.3. Noticed some challenges in driving the rig. After considerable research, I competed the front CHF, safe-t plus, front and rear sumo springs, rear track bar, rear anti-sway bar (I actually have a spare rear anti-sway bar for a F53 18K with shock absorbers mounted parallel to the ground if anyone is looking for one ) and front and rear cermatics wheel balancers. I also realigned my steering wheel. The rig has been weighed, tire pressure based on the weight. All is good :-)

Well everyone has their own opinion but I am pretty sure that a large majority of people here can disagree with you including myself. Suspension improvements are a safety item and when ford builds the chassis they have no idea how they will be used and therefore leave the factory in the exact same condition. Adding the rear link alone stops the sway from semis passing you. If you are happy with what you have then that is perfect for you. I dont believe you should have to make due when you can improve and get a more relaxing ride.

I am thinking the steering stabilizer should be first as it is will assist if you get a blow out. Thoughts please.

Luckily, the only other owner of my 2016 29M Hurricane did some things....very good things. Put Bilsteins all around....all four corners, added a Roadmaster on the front to recenter the steering and put added sway bars front and back. Keep the tires at 82 psi and it's as good as it will get and it's very good. Had a C Class that I had no idea where it was headed....Freedom Elite...had an ACE 27.2 which was better when I went to 75 fronts and 80 on the rears and that was much better but the Hurricane is very good....stable, not much when trucks pass and I can hit 70 mph and not know it....although I like to do about 63-65. IT's sa bunch of money...probably with installation approaching 2 grand but so glad this other guy did it.

I agree with you. F-53's coming off the motorhome factory are borderline stable and dangerous to drive on roads with curves, grades or wind. The mods I've made (Safe-T-Plus, Koni Shocks and a rear track bar) have transformed how it drives. Still not up to DP quality but I don't feel afraid of ending up in the ditch (or in once case the Colorado River) every time a truck goes past or we get hit with a wind gust.

Yeah, unfortunately I dont think there is anything we can do to make it ride like a DP. I had a 34' DP years ago that was brand new and the ride was certainly much better. Difference is I paid $30k more for that option over gas. I love my Thor just fine lol. One thing I wonder though is if air ride might increase the comfort and handling level.

I purchased our 2015 29.3 a couple of years ago and was terrified when the semis passed us! Driving is easier after getting 10,000 miles or so under my belt, but I installed the larger Roadmaster front sway bar and Roadmaster steering assist. Our trip to Florida was much calmer this last January. I'll bet the Safe T Plus products are just as good, I just like the customer service at Raodmaster. I do wish I'd been on this forum before and tried the CHF before purchasing the heavier front sway bar.

I've had a few issues with Thor quality, but overall very happy with the 29.3, also the couple of times I called Thor for wiring diagrams, they were very helpful.

Welcome to the club!!!

Suspension upgrades

Shortly after purchase I completed the following:
*Alignment
*CHF
*Road master steering stabilizer
*Sumo Springs front and rear
*Koni shocks

My MH drives absolutely wonderful, cruise down the highway one handed, semiís pass by with very little reaction to my rig, much easier handling in high crosswinds. Pulling into and exiting driveways at gas stations and other locations much less rock and roll😊
If I had one complaint, is that on real crappy highways like I-65 etc. We still have the shake rattle and roll of the repair joints, bridge joints and patched areas etc.
The only fix to these bad roads would be maybe air ride suspension of a DP?

Adding the rear track bar will correct the sway from semi's.

If you are handy and have access to any metal working machines you can make a track bar for less than $50,

What is the correct part number for sumo springs for a 2019 Hurricane 34j. The f53 would be a 2018. Thanks.

Here’s what I did and it’s actually enjoyable to drive now. Thor Hurricane 27-k
New aluminum wheels-totally changed the harshness of hitting bumps in the front as they are so much lighter allowing the suspension to work better, sumo springs in front, remote air bags in back,-I wanted control of variances of weight and pulling a toad, CHF, steering stabilizer. Also did alignment and found the rear axle mount was welded in the wrong spot causing the wheel to be backwards too far amd not square with vehicle so. Easy to see as well as it wasn’t centered in the wheel well.

You could be right...but I upgraded my 2016 Toyota 4runner (Timbrin suspension, air bags) and the mods (together with sway bars on trailer) helped level the load while towing my 2014 Holiday Rambler Alumalite Ultra. I will report back once I pick up my new coach and let everyone know what I think of the Sumosprings.

Installed the blue Safe-T-Plus and the heavy duty Roadmaster rear sway bar. Better, but still not great, but we don't intend to try anything else. Guessing the big $$ units are much different, but out of my league. So, we're retired, no great rush to get anywhere, we'll stay max 60mph on the interstates and reduce the stress! 2019 Thor Windsport 33x.
I agree that going more than 60 mph is scary! Even if the Sumosprings help, I don't intend to exceed that.

Not getting a lot of love on this! But I tend to agree with you. My last two RVs were on the F53 chassis and Iíve been pretty happy with how they drive as delivered. Just checked the alignment and tire pressure. Mostly it just took a few trips to get the hang of it. I did finally put the Roadmaster steering stabilizer on as I think it might be helpful in a blowout emergency or a wheel dropping off the edge of the pavement (which is what happened to me when an inattentive oncoming driver veered into my lane. There was a moment of considerable terror when I swerved onto a poor quality shoulder!). Iím not sure the stabilizer is better for driving , just different. I am now doing the front and rear CHF because everybody raves about it and it is, after all, ďCĒ. Maybe itíll be transformative!

I own 360 wing sprint cars. One could never tell me little things in the suspension donít do anything. Ridiculous comment. The gf couldnít drive it before upgrading everything. Has no problem with it now. It hugs the road. Itís not like our new Yukon Denali that practically drives itself.

New aluminum wheels really helped with bumps. Weight issue I guess. Hardly noticeable now

Besides the play in the steering wheel, my other main complaint is the rough ride. Hitting a bump or pothole is bone jarring! Has anyone found a fix for the rough ride?

In Ca 55 mph is max if towing. So i do 58 . On my october trip to Arizona and New Mexico speed limit is much higher 70 or 80 i forget. I averaged 65. I feel that is the sweet spot for my mh. It drove great and i got a little better gas mileage

And i also think most of these mh need some mods to make them drive better.

Your absolutely correct.... everyone does have their own opinion and their own experience. I stand by my statement that nothing replaces experience. Many new to motor homes think all these mods are going to make their coach drive like the family sedan. Been there done that.
Just trying to make the point that ainít gonna happen. As I said before, you do learn to compensate without even thinking about and that death grip on the steering wheel slowly relaxes. Itís not my money your spending so if it makes you feel better have at it.
