    What Are SumoSprings?

    Simply put, SumoSprings are oversized bump stops that replace your vehicle’s factory bump stops. Above is a size comparison between the old bump stop (brown) and the SumoSpring replacement (yellow). SumoSprings are over twice the size.

    But there is more to SumoSprings than simply their size. Where bump stops exist to prevent dangerous impact between a vehicle’s main body and it’s chassis, SumoSprings also improve the vehicle’s overall suspension and ride quality (we get to this further below).

    Types Of SumoSprings

    Rear SumoSprings – Everything that we have discussed so far about SumoSprings replacing factory bump stops is in regards to “rear” SumoSprings. These are the ‘springs’ that get installed in the rear of your vehicle.

    Front SumoSprings – Unbeknownst to most, there are also SumoSprings made specifically to reinforce the front load support system. Depending on the vehicle, these van either be similar in shape to the rear SumoSprings or are ‘coil springs’, specifically designed to be inserted into the front coil that surrounds the struts (for Ford Transits and Promasters).

    These Coil SumoSprings support the front strut coil by preventing the spring from over compressing and were highly recommended when we spoke with SuperSprings staff; the manufacturer of SumoSprings.

    "Engineering dept reported...that the front insert was really substantial in providing control in many real road environments just like their customers would encounter."

    How SumoSprings Improve Suspension

    Most vehicles are not originally manufactured with the intention that the driver will load the vehicle up and take it off-road. If you’ve done this before with your camper van or RV, you may have noticed that your ride is filled with rough bumps, jolts, and intense side-to-side sways.

    In fact, we dreaded taking our Transit off-road when exploring BLM & National Forest land. The driving just wasn’t an enjoyable experience.

    More Than Just For Off-Road
    Even if you never plan to go off-road, SumoSprings are excellent in smoothing out your ride when driving over speed bumps, pot holes, and entering/exiting driveways with uneven surfaces.

    “But how, specifically, do SumoSprings improve suspension?”

    SumoSprings Absorb Bumps & Shocks Earlier

    When you replace a factory bump stop with a SumoSpring, you’ll immediately notice that there’s much less air space between the vehicle’s body frame (top) and it’s chassis (bottom).

    You can see this example in the above picture.

    Exact distances will vary. Depending on the vehicle type and overall weight.

    In fact, SumoSprings are engineered to come into contact much sooner than a factory bump stop. This is so that the SumoSpring can begin to absorb the impact from the chassis much sooner than a traditional bump stop.

    The result is a vehicle that experiences: less vertical movement, less body roll, and improved load support.

    Obligatory Engineering-Speak
    SumoSprings are made from a proprietary micro-cellular technology that offers a progressive absorptive cushion under your camper van’s body to smooth out your off-road adventure.

    Are SumoSprings Worth It?

    Absolutely. 100x YES! SumoSprings significantly calmed our ride when driving across uneven terrain. Less side-to-side sway, smoother rides, and less jarring jolts.

    Additional Side Benefit: Our SumoSprings also helped us regain ~3/4" of clearance that we had lost when building our heavy camper van.

    Life Before SumoSprings

    We drove our first 30,000 miles without SumoSprings and still vividly remember the very real hesitations we had when we drove on uneven ground and bad terrain.

    The long list of “bad terrain” that hampered our driving included:

    When we drove on any of the above terrain, the body of our van would experience tremendous movement. From harsh up-and-down movement to intense side-to-side sways it sometimes felt like our van was on a ship in the middle of a hurricane.

    And all this movement sometimes caused our clothes and food to get thrown from their cabinets onto our floor. It wasn’t uncommon to have a huge mess in the back when we finally arrived at our destination.

    A Good Analogy? Imagine a bobble head figure. When you shake the body, the oversized head bobbles from side-to-side with exaggerated movements. Imagine sitting inside the bobbling head as it sways back and forth. That's what we felt in our camper before installing our SumoSprings.

    Life After SumoSprings

    With added suspension support from our SumoSprings, we are much more confident when driving on unmaintained roads.

    Our rides are considerably smoother with less side-to-side sway because the SumoSprings pick up the weight of our camper and dampens it’s overall movement.

    No longer are we weary of driving our Transit camper van off-road. We drive much more confidently and this has allowed us to get deeper into nature to enjoy a more diverse range of camping opportunities.

    And for roughly $300-400 (prices vary depending on the vehicle model), SumoSprings are some of the cheapest camper van suspension upgrades you can make that have an immediate and noticeable impact on your driving experience.

    No expensive installation required: We installed both the front and rear SumoSprings in less than two hours at a Walmart parking lot.

    10/10 we would purchase SumoSprings again for a second camper van build.

    What To Know Before Purchasing SumoSprings

    Before picking up your pair of SumoSprings, there are TWO VERY IMPORTANT things you need to know.

    1. Three Different Colors (And Densities)

    Rear SumoSprings come in 3 different material densities and each density is identified by a different color. The heavier your vehicle, the better off you are going with a denser material.

    For lightweight vehicles and are not intended for camper vans.

    For medium and heavy vehicles. This is the color (density) we chose for our camper van and it fits our needs perfectly.

    For heavy vehicles

    For Our Camper Van: Our camper van weighs ~8,000lbs and we were recommended to go with the medium density (Black color) springs. If your van is heavier than that, the yellow models may be best for you.

    Front Coil SumoSprings only have one density: Black

    2. SumoSprings Are Vehicle Specific

    SumoSpring products are generally NOT interchangeable between vehicle types. This is because each vehicle’s size and specs are a little different.

    Therefore, let us help you select the proper SumoSprings for your camper van. We help you do this in the section below.

    SumoSprings FAQ

    Get answers to the most commonly asked questions below.

    Do SumoSprings Really Work?

    Heck yeah they do! SumoSprings remove much of the unwanted bumps, jolts, and sways from your ride. Picking up a pair of front and rear SumoSprings will do wonders to improving your ride and enjoying your travels when on uneven terrain.

    Are SumoSprings vehicle/model specific?

    Yes. Whether you are driving a Mercedes Springer, Ford Transit, Dodge Promaster, or any other vehicle you will need to find the specific SumoSprings model for your vehicle. We make several model recommendations in the above table of our SumoSprings review based on which vehicle you are driving.

    Do I have to purchase BOTH front and rear SumoSprings?

    No, it is not required to purchase both front and rears. If you can only get one, get the rears. But the sales representative that we spoke with highly recommended us to purchase both the fronts and the rears for the best suspension results.

    Will SumoSprings Increase My Ground Clearance?

    Yes & no. SumoSprings may help you regain any ground clearance you may have lost due to having a heavy camper van. But they will not help you achieve any higher clearance then when your vehicle first came off the factory line.

    In our case, our Ford Transit regained roughly 3/4″ of clearance after installing our SumoSprings.

    But this was due to our front Coil SumoSprings helping to relieve weight pressure off our front strut springs and had nothing to do with our rear SumoSprings.

    How Long Do SumoSprings Last?

    SumoSprings are backed by a lifetime warranty from the manufacturer. They do not leak air, don’t require compressors, and don’t require any maintenance whatsoever. They just work.

    Are SumoSprings Good For Towing?

    Yes, they are! Because SumoSprings help support heavier payloads by reducing squat and sway, these helper springs are a perfect answer to help manage your ride when towing large, heavy objects behind you.

    SumoSprings vs. Timbrens: Which Are Better?

    To be honest here, we have never tried Timbrens. Although we’ve read users generally prefer SumoSprings instead, especially among the RV and campervan community.

    But if you’re looking for a decent comparison check out this post from TruckSpring.

    How To Install SumoSprings On Your Camper Van

    We had no previous SumoSprings experience and it took us about 2 hours to install both the rear and front SumoSprings.

    And we went pretty slow.

    This video from Carey On Vagabond does an awesome job at explaining the installation process for both the rear and front SumoSprings on their Promaster camper van.

    Dollar-For-Dollar The Best Vehicle Suspension Upgrade You Can Make Right Now

    For the most cost-effective camper van suspension upgrade, we think purchasing a pair of front and rear SumoSprings are the best way to go. In our opinion, SumoSprings are much more worthwhile than investing in a 4×4 camper van.

    Whether if you’re looking to get SumoSprings for your Sprinter, Promaster, or Transit, we say just stop thinking about it and pick them up today. You won’t regret it.
