Keep your Dodge Promaster from sagging!!
SumoSprings for the rear end are great if your vehicle is pulling a trailer or carrying a heavy load. They will stabilize your vehicle and help to keep it level. Made as rear alternative to traditional air bags by Air Lift and Firestone. These micro-cellular springs differ in that they require no inflation and will not leak or rupture. While not adjustable like air bag helper springs, Sumosprings will help to reduce sway and reduce sagging in the rear end. Just mount and forget. Included with all kits are steel mounting brackets and hardware. All are custom fit for a simple installation.

  • Rupture and Leak Proof
  • Simple no-drill installation

  • Made in the USA

Nice upgrade
Installed both rear and front sumo-springs at the same time. They lifted the rear about 1.25" and were easy to install once the rear end was safely lifted. With both installed on my 2018 Travato 59G it firmed up the ride and the vehicle is less susceptible to cross winds.

Must have for Promaster Vans
Easy install, took most of the sway out of the rear of the camper van. The van feels topheavy from the factory and the Suma Springs took a lot of the "tippy" feel out of driving the van around corners.

Great Product/Fast Service
This was a highly recommended product for it's ease of installation and better ride and control. Complete and easy to follow instructions were included with the product. I'm very impressed with the simplicity (no extra attachments needed) and the fact that it's a set it and forget it part. Install and enjoy a better ride.

easy upgrade to suspension
Super simple install on my motorhome. I have used Sumo Springs on my last 4 vehicles and have never had a failure with any off them. Makes for a secure ride. Reduces sway from cross winds and passing traffic. I have used this on Ford, Chevy and now the Dodge ProMaster. Don't even have to remove the tire. Jack up the rig, remove the bump stop, thread the sumo spring into where the bump stop was and hand tighten. Repeat on the other side and done. Really stabilizes the rig. Of course get it from Suspension Connection. Best price I could find anywhere and outstanding service. Quick delivery.

Sumo Springs for a Winebago Trend Class C
The Sumo Springs arrived in a very resonable amount of time. They had satisfactory instructions and were easy to install with a floor jack. I haven't had a chance to check them out for a lengthy drive yet but will this coming January.
