Has anyone been able to improve the ride of the 2015 Thor ace class a motor home?
When going over expansion joints and slightly rough road surface there is a lot of annoying shaking and noise going on to the point one cannot hear the audio system.

Glad you are able to join us.

Try contacting these folks: https://www.facebook.com/SuperSteerParts or their website directly: RV & Truck Parts - Suspension – Steering – Brakes - Towing. They have a great line of products to help reduce this problem.

Happy trails,

Rick Y

Can't recommend unless we know the chassis and engine???? If it's gas it's probably the F-53 with the V-10. The year makes a difference also.

You are correct. The OP mentioned it is a 2015 ACE 27.1. I got mine delivered today, but they (the dealer) are storing it for me until I can get a space.

Personally, I didn't notice much noise, it was a tight ride. I will still have a steering stabilizer installed. If for no other reason, a state of mind.


Phillip Sosi, Did you check the air pressure in your tires?

You need to weigh your rig and set the tire pressure according to the tire makers weight chart.

Over inflated tires will beat you to death.

Tire have been checked to proper inflation.

Unfortunately, harsh ride over expansion joints and the like are part of the nature of the beast with solid front axles used on most gas motorhome chassis. Diesel chassis with IFS and/or air bags generally have a better ride.

You say the tire pressures are correct, but how did you determine that? Are the pressures set according to the manufacturer's recommendation on the sticker or have you actually weighed the rig? And if you weighed it, did you weigh all 4 corners separately?

Adjusting tire pressures according vehicle weights as determined by an actual 4-corner weighing is a good starting point to minimizing harshness. Changing out the shocks to something like Koni FSD may also help.

Philip,
There are things that you can do to help. There's a TON of information on these threads. It is always best to start with the tire pressure located inside on a sticker for your coach. Set it for that pressure and put some miles on it and get back with us.
While you are traveling read about the CHF (Cheap Handling Fix). Don't know if you can do that with the 2015 chassis. I herd rumor that there were not two holes in the front stabilizers (SB) so I don't know. Let us know and we can advise.
