Sumo Springs

[KFitz]

FR3 32D 2021. Overall, I guess I'm happy with my RV but I hate hate the noise while driving. I drive in my noise cancelling ear buds which I know is not safe. But I hate the noise. Any ideas? And also, I am thinking of installing Sumo springs, does anyone have any insight on the on my vehicle? Would self install, hubby a diesel mechanic so he thinks its an easy installation. Just would like to help the ride especially on bad highways, TIA

I put the 1000lb. versions on my F150 and like the results but have no idea whether you'd like the result or not.

For me, they greatly reduced body roll, without stiffening the ride too much. There is about 1.5" of free axle travel before they engage. So, daily driving isn't affected much. Kinda the best of both worlds.

I like that they are silent, progressive action, have that free travel space and basically nothing to go wrong, no maintenance and easy installation.

But there is a lot of difference between an always loaded vehicle like yours and a PU, that has a dual life as tow vehicle and daily driver.

A comparable product is called Timbrens. Timbren.com I have had a set on my truck for years and love them. Very stable and keeps the truck level with no bounce or sway.

I have installed Timbrens as well, and have been very happy with them. They do seem to slightly increase harshness of ride.

I had Timbren Helper Springs installed on my 31' Class C. Best upgrade I ever did, value for the money. Next best upgrade were tunes to alter the shift points from UPFORD.

Timbrens eliminated most expansion joint and road bump noise. They help just enough to lessen body sway although I didn't have a complaint about that issue until it stopped

I did Sumo Springs on our 2020 Coachmen Freelander 27QB. On a Chevy Express 4500 chassis. I also did Bilstein shocks at the same time. Both we self install. Not difficult and if you have a mechanic in the house it should be no problem.

Sumo springs reduced roll and actually made the vehicle more stable when it was parked as we walked around inside (no jacks set). The ride was overall quieter. Couple of benefits we did not really expect but appreciated.

I’m sure that both the Bilsteins and Sumo Springs contributed to the sound reduction and ride improvement and would definitely do both again.

I picked the SumoSprings over the Timbrens, for my F150.
I prefer the more modern micro-cellular polyurethane, over old school rubber.

Timbren Helper Springs? Might be old school rubber but aren't they also infused (maybe not the correct technical or Timbren marketing term) with bubbles?
