SuperSprings SSF-170-40-2 Front SumoSprings

Greatly improved the ride and on our Windsport 29m. Easy install. Would recommend this product.

This product completely transformed our ride. Before the installation it seemed any bump no matter how small sent shockwaves through the A-class. I was skeptical at first especially given the fact they are $700+. However, once I installed them (in about an hour) I was pleasantly surprised. The suspension is incredible now. The springs absorb so much of the shock and really make the rig more pleasant to travel in. Our suspension isn't that old 2-3 years so even on a fairly new rig this product really makes a difference. I haven't decided if I will purchase the rears but perhaps in the future. The installation is not difficult but I think it could use some better pictures and further explanation of the orientation of a couple of the components.

Added the sumosprings to my Holiday Rambler on the F 53 chassis. Relatively straightforward install. The first one took maybe an hour to install, second one took like 30 minutes once I understood how to put it on… makes a huge difference from the terrible stock bump stops.

These are an excellent product, which does reduce roll by 50%. Best thing i have added to my 2004 Ford Coachmen Mirada. Makes her even more of a pleasure to drive.

Improved the ride and handling.

F53 front end Bounces now since the opening between the frame and the leaf spring mounted Suma Spring is now Zero. There is significant bounce on large "lift" ramps encountered on the open road from poor road maintenance crews. You can either see the "ramps" I call them or not before you can try to slow down to prevent the huge bounce from occurring. Prior to installation, the suspension would absorb this blow. Note that you should stay away from California's 405, 118, I5, etc. as there are numerous ramps that can (and almost) send your rig into the other lane. Now for the positive stuff. Assume there is a road left in America that hasn't been rutted, grooved, uneven or physically destroyed (like in Colorado) you can drive straight on... okay there are very few, the Suma Spring actually makes the rig ride like a car with no swaying back and forth as though you were on a ship at sea. And, the steering seems to flow tighter like a car. Just a heads up on the bouncing.

Installed the product to improve the ride of our 30’ gas, class a motorhome. The factory supplied bump shocks gave no relieve from the pot holes and patches on the highways and the ride was terrible. The installation of the SumoSprings was very easy and straight forward and the ride at highway speeds has improved significantly. There is also a moderate improvement with cross winds and the impact of 18 wheelers passing us. I would highly recommend these SumoSprings.

Have a 2010 F53 22.5k chassis RV. Have already done the CHF on the front end but wanted to soften the ride more. Bought these, installation was easy, took me 2.5hrs and most of that was greasing the front end (I'm just an average home mechanic skills so they are dead simple to replace). Instructions were clear, not complicated to read. Everything fit and worked properly. Wow the ride is a difference, my front is probably gonna be a comfortable place to be on long drives. Recommend it. Worthwhile upgrade to a gasser RV; makes it more comfortable. OH YAH, remember to grease your front end (9 locations on the F53 chassis) as well - I hadn't done that and took the time, while I was down there to do it.

Installé sur un frame F-53 2008. Lors de la première sortie après l’installation, mon premier commentaire est WOW. On ne ressent plus tous les défauts de la route. Toute une amélioration. J’aurais dû l’installer avant! Les Sumosprings avants s’installent très bien soi-même en environ1 heure pour les 2 côtés.

Really made a big difference in the handling of our motor home

Just had them Installed on my winnebago vista (2018). the drive seems to be better then before. no longer feel like i'm driving a boat! (swaving).. Driving down to Mexico (from Canada). that will be a better test.

Made big difference in handling
