Most Popular SuperSprings Intl for 2005 Dodge Grand Caravan

Our 2010 toyota sienna def doesn't sag as much with our full load of 2 parents, 5 teens, and our luggage. No more scraping of our attached hitch on the driveway apron. Since they have progressive resistance, the ride is still comfortable when not under load, but well-supported when loaded. Install was a damn wrestling match - def NOT as easy as the video. Ultimately I'm glad I chose these over the airbags bc now that they're in, they are maintenance free. One note, the version I got did not have holes for zip ties like a preview video had. I'm not concerned about that though bc of the tight fit, there's no way they're falling out.

Easy to install on 2020 Mercedes Metris Cargo Van if you remove tire, clean spring and use soapy water to lubricate coil. Reduced "squat" about 3/4" for ~325 Lb. trailer tongue weight without weight distribution hitch.

I have a Black Series HQ15 off grid off road camper caravan. The HQ15 weights 6000 lbs empty. I have a 2013 F-150 4x4 super cab 5.0 liter max tow package truck! After installing the Sumo Springs the sway and squat of the truck was improved tremendously!

Installed the CSS-1168R Coil SumoSprings Custom Helper spacers on a 2011 Honda Ridgeline 4 wheel drive rear springs. Installation took about 45 minutes including removal of tires. Once spacer was started the installation was easy. Zip ties were a little more difficult because of the dust strut covers installed by Honda.

About all I can say for these is that they did raise the back of my Expedition EL about a 1/2". However, they didn't stay in place for even a year. As far as helping the ride of the truck with the travel trailer, I *think* it helped, but I really don't know if it is anything more than the placebo effect. I removed them before having Bilstein 5100 series shocks installed, with the spring collar set to raise .4", which did make a noticeable, positive difference in the way the truck handled when towing.

Install went fairly easy once I figured out the best spot to put the jack to lift the van. Really helped to have an oil filter wrench to get the old springs off the back. Took it out for a drive after an much better cornering and much less effect from wind and 18-wheelers. This was on a fairly windy day. No big difference in softness of the ride.

I ordered these for my RAM Promaster 3500 because I had heard from fellow owners that they are a worthwhile addition, for increased stability on the road. The instructions are good, and they weren’t too hard to install myself. They are kind of expensive for a couple of rings of dense foam/plastic, but I guess they must be petty heavy duty. I look forward to my next trip to see how they perform.

The Super Springs work great! I pull a 8,500# trailer with a hitch weight of 950# with a 2004 GMC Sierra 1/2 Ton. The truck pulls fine but even with an equalizer hitch still had some sag. The Super Springs were easy to install and leveled the rig. After a year everything still works great.

These "helper" springs made the difference between towing with our E150 Ford conversion van or buy a different vehicle. Our tow vehicle rides a little stiffer, but that was expected. It certainly gives us the confidence of towing a 26' camper.
