Is this pretty much a "do NOT do it yourself" project?

I was thinking that I could use the leveling jacks to get the tires off the ground...

It was easy on my Quantum GR22.

Is your rig on the 350 Chassis?
I wonder how much difference there is (if any!); in installing them on a 450?

Sorry to drift off topic for a second.

peeled the stickers and machine buffed..

we haul 2 rzr1000"s , and go to the dunes a lot... we set up the trailer to be able to get out of the wind at the dunes, you'd be surprised at how many people we end up with in there..

I installed them on my Thor Outlaw and have had great luck with them. I installed myself, but I have the equipment and experience to do it. To do a quality job, you will need to remove front tires and definitely the rear tires. Do not trust the leveling Jack's to support the rig. To many things can go wrong. You will also need quality drill bits as the frame rails are hardened and cheap drill bits go south long before you get the job done
The job is not really difficult, just lots of big stuff to deal with. Best pricing seems to come from Amazon
Good luck and be safe

I installed a set, (rear) myself. Very easy. Used my leveling jacks to lift, then blocked it. All but one hole was easy to drill. Needed to template the last and drilled from behind. 1000miles so far and very pleased. I added for a stiffer rear suspension as I have a motorcycle lift on the back.

We put Bilstein comfort shocks on and we did not need Sumo Springs.

Chateau 23U (Class C) has chevy 3500 chassis and is lightly sprung (rides much better than previous 4500). On a washboard road the front end bottomed out misaligning the front end. I put Sumo bump stops on the front end and solved the problem at less than $100. Easy to install. Problem solved!

Hello Jerry B, I have a 2016 25.2 Vegas and I put the sumo springs on the front. I measured the front top of wheel well to floor before and after. They actually raised the front end up right at 3/4 inch. I have only driven around 15 miles a month to exercise it We have not been on a trip with them. I replaced the anti sway bars front and back with Hellwig and I added a Safe t Plus steering stabilizer. Now there was a huge positive different in handling with those 2 additions. 4 Koni shocks have been ordered tonight. Last year I took the factory steering stabilizer off and it was worn out at 20k miles. I made the suspension up grades little at a time. Well good Luck and your certainly on the right path.

I just installed the black front Sumo Springs on my 32 foot 2017 Thor Chateau 31W.

Primarily bought these to reduce the buffeting and loss of control caused by semi's and other large vehicles as well as crosswinds. I just white knuckled my coach across South Dakota, Wyoming, and part of Colorado for over 10 hours during high winds...I finally decided enough was enough.

My goal was to make suspension upgrades that give me the most bang for the buck that are relatively quick and easy to install.

So far I am impressed. I drove briefly on the highway during some high winds and I felt a lot more control.

In particular I was impressed with the low speed handling, much of the excessive roll when making left or right turns is gone and the porpoising and side to side sway is greatly reduced.

I was so impressed that I wanted to add the rears...but they cost around $600.00 for the pair...ouch!!!

Instead, I ordered some rear Bilstein shocks (just over $200.00 for the pair) and a $120.00 Bilstein steering dampener. When it is all said and done I will have made some fairly significant suspension upgrades for a relatively low total $500.00 in parts (Front Sumo Springs, rear Bilstein shocks, and Bilstein steering dampener!!! I am going to do all of the work myself.

The cost for the Sumo Springs is in the same ballpark as two front Bilstein shocks (I paid $185.00 for them from Amazon) ...but seriously...if you install them I really do not believe you need to get a front sway bar or upgrade the front shocks. Plus, they are soooo easy to install if you have front jacks...it took me around 30 minutes.

Looking forward to seeing how adding the rear Bilstein shocks as well as the Bilstein steering dampener continues to help how the coach handles.

I may eventually add a Heilwig rear sway bar...but I am already so impressed with how well my coach drives after only adding the front Sumo Springs I really do not think I will want to do anything else.

I will post an update after I add the other parts and take my coach on our next 4 day trip to Glenwood Springs and back.
