Sumo Springs

After reading several reviews on the Sumo Springs, I ordered a set for the front and back of my Class A Winnie Adventurer 35P.

I weighed it and adjusted the air pressure in the tires, installed a TruCenter on the front, had the front end aligned and installed a Blue Ox Track Bar on the rear. It drives a lot better but I am hoping for even more improvement.

I have been doing my own installations so I will be installing them myself in the next few weeks!

I installed them on my gasser, 35' Did not get my $$$ worth. Hope you have better results. A rear sway bar would be the way to go in my opinion and that would be my next thing except my rig handles quite well as it is.

The Sumo Springs come in two different setups. The less expensive set basically replaces the factory bump stops (about $500) and the other system has a lot larger Sumo Spring that is installed via brackets, etc and is about $1200 for the set. Which system did you install?

If you installed the heavy duty set and didn't see much improvement, it isn't too late for me to change my mind.

Was able to install the front set by noon Saturday. Not too hard but I found a shop that will install the rear units. The hardest part was putting the wheels back on. Those dudes are heavy!

The shop couldn't get to me so I installed the rear units myself. Now to put the wheels back on. Discovered that one of the attachment brackets on my rear sway bar is broken so most likely that is the main problem with the side to side sway. Will fix today.

sumo's

I installed them on my Itasca front & rear It did help with the ride smoothed out the bumps,was able to put them on without removing the rear wheels,one hole had to be drilled on each side but other than that they went on pretty easy.matched them up Koni's. I still might add a rear trac bar but am happy with the results.

I had to drill one hole on each front side but had to drill four holes for each rear unit. A tire shop is on its way to put the rear wheels back on. They are just too heavy for this 69 year old!

Drove our MH on a narrow, rough county highway near our house. World of difference! Much smoother and there was no need to make steering corrections!

HI,

I just have one question did you torque the front tires and how did you lossen them. The wheel lugs are torqued for 450 lbs.

Good Luck!

My half inch impact wrench removed the lugs but I paid a service truck to come out. They put the wheels back on and he torqued all the lug nuts. Cost was only $75.00!

is removed for the Sumo Springs, the front stop or the rear stop.
