SumoSprings Front Helper Springs for Ford E Series & Mercedes Sprinter Vans (SSF-106-40) from Nomadic Supply Company are 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 Mercedes Sprinters are manufactured from proprietary closed micro-cellular urethane providing a smooth and progressive spring rate with superior damping properties.
The SumoSprings Front Bump Stops for the Mercedes Sprinter (SSF-106-40) replace the factory bump. SumoSprings Front Helper Springs for Ford E Series & Mercedes Sprinter Vans (SSF-106-40) contacts 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 and improves control in high winds, and comfort while the suspension cycles.
A heavy front load can cause front-end 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 upgrade your vehicle’s factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.
SumoSprings Front Helper Springs for Ford E Series & Mercedes Sprinter Vans (SSF-106-40) provide 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.
The SumoSprings Front Helper Springs for Ford E Series & Mercedes Sprinter Vans (SSF-106-40) can also compress by as much as 80 percent to support a heavy front load and to help your factory suspension bear up under the load. 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 means that you have improved 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 Helper Springs for Ford E Series & Mercedes Sprinter Vans (SSF-106-40) work 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 Front Helper Springs for Ford E Series & Mercedes Sprinter Vans (SSF-106-40) compress vertically with minimum expansion to the sides, so they won’t be damaged by nearby mechanical parts and they fit safely into tighter spots. And unlike air springs, SumoSprings require no maintenance or adjustment.
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 SumoSprings Front Helper Springs for Ford E Series & Mercedes Sprinter Vans Vans (SSF-106-47) or yellow for the additional support as well as the vibration reduction.
On the other hand, if you’re a weekend warrior with a lightweight Sprinter build, our blue SumoSprings Front Helper Springs for Ford E Series & Mercedes Sprinter Vans (SSF-106-40) is the way to go because it gives you all the support and control you need, without affecting your factory ride quality on daily driving.
