Smoothing the Ride

[RovinOn]

I've seen the SumoSprings by SuperSprings International advertised in this months edition of MH Magazine.
As anyone tried them or use their other products?
I'm looking to use the SumoSprings on my coach to hopefully help smoothout the ride and decrease my dashboard bounce.

Any thoughts? Would appreciate your thoughts before purchasing.

Some guy over on rv.net seems to think they are ok.

oemtech,,, Thanks for the heads up!
With what he had to say and the article in MH I placed an order to try the front ones. I'm sure they can't make it any worse!

Be sure to keep us updated...

Will do! They were very helpful and courteous in placing the order and will try to have them to me in the time frame needed.
I'm hoping they are as good as they say !

Had the front Sumosprings installed last week. Thought the price was cheap enought to give them a try. Only driven motorhome from shop to home (about 10 miles) Did about 5 freeway miles and the ride seemed to be a little smoother going over expansion joints. To early to give full report. Heading to Balloon Festival in a week. After a couple of thousand miles I should be able to give a better eval.

Great! √

Had an interesting follow up call from one of their techs just a little while ago. She was confirming my information so I could recieve my springs as I needed them. As we continued to talk she gave me a few installation tips as to get the best performance from them. She did the same with the rear kit so that I know when I decide on the purchase of those.
One thing she did state though was that once they get their distributorship up to handle these they no longer will sell to the general public. So now is the best time to get their entry level prices because once the distributor comes into play they will go up!
She quoted me the prices now so I would know later when my dealer quotes them.
She was a very informative person to speak with! They want to know our feedback as well, right now it is very important to them.

Huh..A foam shock absorber. What a novel idea.

Appears to be a larger version of a Like-Air frame bumper we already have.

Do these Like-Air bumpers need any maintenance?

Should I worry about getting anti corrosion fluid (Fluid Film) on them when I spray the rig's bottom?

Thanks,

Preston

Please see the graphic below:

This “Like-Air” auxiliary spring is a multi stage autothane unit that does not require maintenance or adjustment. Workhorse utilizes three “Like Air” auxiliary springs depending on the GAWR. The 6,500 lb., 7,000 lb., 7,500 lb. and 8,000 lb. front suspension utilize a white auxiliary spring 5.196” tall, Workhorse part no. W0000431. The 8,500 lb. front suspension utilizes a gray auxiliary spring 5.196” tall, Workhorse part no. W0002592. The 9,000 lb. front suspension utilizes a white auxiliary spring 3.622” tall, Workhorse part no. W0002002.

The front SumoSpring is to replace the Jounce bumper on the front and is a little larger.
I'm hoping these do what they say, I was considering having air bags installed on my coach.

Air bags have been used by OEMs in the past (Rexhall) to level out a coach. The benefit of improving the quality of the ride using air bags may be there however I'm not sure how well they will perform without extraordinary engineering.

In the CCP Stabil-Air system we saw were the full length springs were replaced by half length springs and the trailing part of the spring was connected and the axle supported on a self-leveling air bag. (leveling system worked poorly and was dropped from production). The suspension modification took 3 days to accomplish and was over $5,000.00.

Although Camping World carried this system as a SKU in their system for a brief period of time, not that many customers stepped up for the Stabil-Air system. If you searched "Google" you may still find one of these things out there on eBay.

The best thing that came out of this project in my opinion were the shock absorbers; The Koni FSD.
