Timbren rear helper springs

[jabrabu]

I have a 2018 Chateau 31E. I have already gotten a custom alignment, installed Helwig swaybars, a Saf-T-Plus steering controller, and Bilstein HD shocks. It drives well now, but these big 32 ft. class C's are really heavy at the rear, at or near the rear axle weight rating, so I thought it could use some sort of helper springs.



According to etrailer, there aren't helper leaf springs that fit my RV, and even the Sumo springs aren't shown as fitting. I didn't want to mess with airbags, since I wanted something with zero maintenance required. So I installed these Timbren rubber springs. They just replace the existing bumpstops. The photo shows the stock bumpstop next to the Timbren.


With the RV empty, no cargo, and winterized with no water, they sit just a hair above the rear axle. With a load they will compress and add some spring rate, which I think will help.


They also make them for the front suspension, but I don't feel that the front really needs them.

They appear to work the same as SumoSprings: which is not a bad thing at all!

With respect to the Safe T Plus steering controller, did you upgrade from a factory install or was there none at all before your install?

They're essentially the same as SumoSprings. I've used Timbrens on my last three bumper pull tow vehicles, mainly to help with reducing porpoising on bad highways. They work well.

Yes: they sure do!
They came standard on my rig.

There was something there from the factory, but I think it was just a steering damper and didn't have the self-centering feature of a steering controller.

I'm a big fan of the Sumos, but Timbrens have the same reputation. Just remember that nothing you add will increase the weight rating of your rig, only assist the rigs ability to carry said rating.
