Questions about SumoSprings?
Should I use SumoSprings or SuperSprings?
Are you an RV owner? Do you own a truck/van used for recreational purposes such as towing a boat or trailer? Are you looking for a smoother ride and want to damp road noise and shock? Do you take your vehicle over rough terrain or off-road? If so, it sounds like you should check out SumoSprings.
Why are SumoSprings different colors?
The different SumoSprings colors identify the density. SumoSprings are manufactured in three densities: -40 (Blue), -47 (Black), and -54 (Yellow).

What is the difference between air bags, air springs, and SumoSprings?
SumoSprings and air bags are types of air springs. The main difference between SumoSprings and an air bag is the way the air is captured and controlled. A traditional air bag requires a compressor with hoses and valves used to fill the balloon inside the air bag. This system requires maintenance to prevent cracks and/or leaks. SumoSprings capture air in millions of air pockets inside the micro-cellular urethane material.

What is the capacity of SumoSprings?
The capacity of SumoSprings varies depending on the height, diameter and density of the spring. SumoSprings are rated by how many pounds of pressure it takes to compress the spring down to 50% of it’s original body height.

Are sumosprings used for carrying heavy loads or ride comfort?
Both! SumoSprings work in conjunction with the original equipment to share the load, enhancing the carrying capacity. The micro-cellular urethane SumoSprings are manufactured from is known for its damping properties and reducing road shock and vibration. This helps create a cushion-like effect, perfect for maintaining and improving ride quality.

Questions about SuperSprings?
Should I use SuperSprings or SumoSprings?
Does your truck/van have rear leaf springs? Do you regularly use your truck/van to carry heavy loads? Is your truck/van setup with a service body? Is your vehicle a crane truck, wrecker truck, tow truck, or other work industry truck carrying a lot of weight? Are you experiencing excessive rear-end sag negatively effecting drive-ability? Does your truck/van have noticeable body roll and poor handling while unloaded or loaded? If so, it sounds like SuperSprings are a great match.

Are SuperSprings the same as helper springs?
The answer depends on your definition of helper spring. If you think a helper spring is an "add-a-leaf" or "overload spring", then the answer is no. By simple definition, yes, SuperSprings are helper springs as they do help the original suspension components of your vehicle - and more!

Are SuperSprings leaf springs?
SuperSprings are a suspension stabilizing system, not a simple spring. SuperSprings do utilize a leaf, or semi-elliptical, spring and are used in conjunction with and in addition to leaf spring assemblies. They are an enhancement, not a replacement to leaf springs.

Do SuperSprings increase my vehicle's GVWR?
No, nothing can increase your GVWR. The GVWR of your vehicle is set by the manufacturer and it cannot change and you should never exceed your vehicle's GVWR. SuperSprings and all other helper springs are intended to help level loads, not increase GVWR.

What shackle hole should I use?
SuperSprings are designed with various shackles. The shackles will have 1, 2, or 3 bolt holes. The bolt holes allow the installer to adjust the pre-load tension of the SuperSprings. The higher the hole, the more pre-load tension, allowing the SuperSprings to start higher on the spring rate curve. This is useful for applications with uneven loads, for example, crane trucks. The SuperSprings on the crane side of the truck can use the upper bolt holes, while the non-crane side SuperSprings use the lower bolt holes. These bolt holes, and the varying positions, can also be changed by an installer to accommodate varying ride quality preferences.

Questions about Trailer SumoSprings?
How do Trailer SumoSprings work?
Trailer SumoSprings are a SumoSprings Solo air spring mounted to trailer leaf spring assemblies using unique steel brackets. As the frame lowers from weight or sway, the SumoSprings engage the frame, bearing some of the weight and limiting the load on the leaf springs.

Does SuperSprings International fix broken trailer leaf springs?
Trailer SumoSprings are an enhancement to trailer suspension systems, not a replacement to failed suspension components. SuperSprings International does not manufacture leaf springs.

Questions about Coil SumoSprings?
What is the capacity of Coil SumoSprings?
Coil SumoSprings can be used on any application equipped with coil springs and has a GVWR under 14k. They have been tested on trucks, passenger vehicles, sedans, specialty utility vehicles and more. From these tests, SSI has determined that Coil SumoSprings consistently increase the capacity of the coil springs by 15% to 30%.

Are Coil SumoSprings like other coil spring inserts?
Traditional coil inserts change the structure of the spring itself by creating separate functioning sections. This split increases coil capacity because it generates stiffness. However, this also decreases coil spring articulation and ride comfort. By using Micro-cellular urethane, the Coil SumoSprings act as a spring within the coil spring. Not only is capacity increased by the change in the spring structure, the progressive nature of the Coil SumoSprings also enhance ride comfort.

Will Coil SumoSprings help my minivan or sedan’s suspension?
Absolutely. Coil SumoSprings are very popular on mini vans with bike racks, camping accessories and other equipment. Coil SumoSprings will increase coil capacity to help reduce sag and sway. The same is true for sedans, SUV’s and other crossovers. Some people choose to use Coil SumoSprings on these types of applications simply to tighten up the handling of the vehicle.

Questions about SuperCoils?
Will SuperCoils lift my truck?
Some SuperCoils are intended to provide additional lift from stock ride height, typically by 1 to 2 inches. This would be a functional lift to provide additional load support for the vehicle. Other SuperCoils are designed to maintain the vehicle’s stock ride height. Please check the “notes” when using our vehicle lookup to determine whether or not your particular application will be lifted.

Questions about SuperStops?
When and why would I want to use SuperSway-Stops?
If you are using air springs on the rear of your vehicle and it is equipped with a top overload spring, you are probably unhappy with the amount of sway in the vehicle. This is because your air springs lifted the chassis up higher from the top overload springs, rendering them useless. The overload spring will not provide any benefit unless it is engaged. By filling that void with SuperSway-Stops, you're allowing the overload spring to engage earlier. Once engaged, the SuperSway-Stops resist and have a progressive spring rate just like SumoSprings.

Can I use SuperStops without an auxiliary spring?
No, SuperStops are only applicable for vehicles equipped with a top overload spring.

Are SuperStops the same as auxiliary spring contact pads?
Yes and no. SuperStops are the same as contact pads in that they replace and bolt in the same place as contact pads. They are not the same in design and function. Contact pads are typically thin pieces of rubber. SuperSway-Stops are a tall piece of micro-cellular urethane. SuperStops are designed to be engaged, allowing your top overload spring to do the work it was installed to do.

Questions about Mounting Kits?
How do I know if I need a mounting kit?
SuperSprings installations use either a Mounting Kit, Poly Spring Pad mounting block, or mount directly to the axle. PSP mounting blocks are included with SuperSprings and do not need to be purchased separately. Some applications require the MTKT or the MXKT mounting kit. These mounting kits are purchased in addition to the SuperSprings. In our vehicle lookup, refer to the column titled "Mounting." This will indicate what PSP is included or what mounting kit is required.
