The SumoSprings Front & Rear Air Helper Spring Kit for Ram ProMasterVans (K-30-009) from Nomadic Supply Company includes our SumoSprings Front Coils for Ram ProMaster Vans (CSS-1195) and our SumoSprings Rear Helper Springs for RAM ProMaster SSR-313-47.
SumoSprings Front & Rear Air Helper Spring Kit for Ram ProMasterVans (K-30-009) is a patented suspension product designed to enhance load-carrying ability, stabilize sway, and improve overall driver control and ride comfort. They are maintenance-free, do not leak air, and do not require any air lines or compressors. SumoSprings Front Bump Stops for Ram ProMasters are manufactured from proprietary closed micro-cellular urethane providing a smooth and progressive spring rate with superior damping properties.
The SumoSprings Front & Rear Air Helper Spring Kit for Ram ProMasterVans (K-30-009) replaces the factory bump stop. SumoSprings Front Coils contact the control arm at ride height to increase the front suspension spring rate, while still compressing to the height of the factory bump stop. Suspension travel is not reduced. The additional spring rate reduces sway, improves control in high winds, and increases comfort while the suspension cycles.
A heavy front load can cause the front end to sag as your factory suspension compresses under the weight of the load. This means that the front axle is trying to support not only the extra load but also the weight of your vehicle. And because there is less weight on your rear axle, your rear tires make less contact with the road, which causes problems with traction, steering, and braking. SumoSprings upgrades your vehicle’s factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.
SumoSprings Front & Rear Air Helper Spring Kit for Ram ProMasterVans (K-30-009) provides progressive load control – the more you load them, the stiffer they become. With a lighter load, the springs will compress easily for soft engagement and a less bumpy ride. The closed-cell urethane material allows for smooth contact between the springs and your vehicle, and the springs act like a shock absorber to dampen road vibration. This evens out the weight, which levels your vehicle and ensures that your rear tires are making better contact with the road. A level ride improves driving control, ensures safe headlight aim, and helps to minimize sway. The springs also support your factory suspension, which helps prevent sagging and reduces bottoming out.
SumoSprings Front & Rear Air Helper Spring Kit for Ram ProMasterVans (K-30-009) works independently from one another to support each side of your vehicle. This action helps to reduce body roll when you make a sharp turn. This also helps compensate for an off-center load.
These microcellular urethane springs are tough. They resist abrasion, oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from -25 F to 200 F (-33 C to 93 C).
SumoSprings are not made from rubber. They are a progressive spring with a very soft initial engagement. That means that as more weight is added, the harder they get and the more they push back, providing support and control when you need it without affecting the factory ride when unloaded. These are a suspension enhancement built to create a better journey. Manufactured from our micro-cellular polyurethane, they are designed to reduce rear-end sag, decrease vibration, stabilize sway, and soften harsh rebounds.
How to Choose the Correct SumoSprings Color for Your Vehicle:
Our blue SumoSprings are the most common density in most applications. That’s because the blue SumoSpring provides really good support, reduces vibration, and fixes sagging and body roll. Plus, this density doesn’t impact your unloaded ride; that’s really the key here — unloaded versus loaded.
If your vehicle is constantly loaded like a built-out camper van or a truck with a camper on it full time, then you’re going to want to go with a higher-density product like our black or yellow SumoSprings for the additional support as well as the vibration reduction.
On the other hand, if you’re a weekend warrior with a lightweight Promaster build, our blue SumoSprings are the way to go because they give you all the support and control you need, without affecting your factory ride quality on daily driving.
