I have ordered a couple items from etrailer and always have a good experience. This item was packaged properly and easy to install. The instructions were easy to follow and there was extra hardware in case it was needed. I haven’t towed it with them installed yet, but I feel confident they will work as advertised.

This product came with a mounting bracket that did not fit my spring plate correctly. I called etrailer and the lady I talked to was very helpful and even contacted Sumo Springs for me to help with my concerns.They told her that they hear of this often and its ok to mount on the spring plate even though it doesn't fit correctly. etrailer was great but I'm disappointed that sumo springs don't supply a bracket to address this different spring plate.I have sumo springs on 3 other vehicles that I have owned and installed them on other vehicles with no issues.Come on guys supply a bracket that fits.

Ask the Experts about this SuperSprings Intl Trailer Leaf Spring Suspension

  • Troubleshooting Inside Tire Wear of Rear Axle of Fifth Wheel Trailer
    If you are getting inside tire wear on the rear axle of your fifth wheel that would indicate that your trailer is sitting a little nose high and putting additional stress on the rear axle. If you look at your trailer when it's connected to your tow vehicle does it sit level? To lower the nose you could lower the head of your fifth wheel hitch or raise the pin box up in the mounting brackets of the frame.

  • SumoSprings Suspension Enhancement Kit for Trailer with Tandem 5,200 lb Lippert Axles
    The SumoSprings kit part # SS26MV would work great on your tandem axle trailer that has 5,200 lbs and cushioned equalizers. This will give you additional support and smooth out the ride quality as well. This kit is also listed as TSS-107-47 which might be where some of the confusion comes from.

  • Could SumoSprings SS26MV Fit 2021 Forest River Sabre 37FLL

  • Correct SumoSprings For 2021 Grand Design Solitude 380FL With Tandem 7000lb Axles
    I would be happy to help! Since your 2021 Grand Design Solitude 380FL has tandem 7000lb axles you will need either the SumoSprings Trailer Helper Springs # SS26MV if your trailer has overslung leaf springs (leaf springs on top of the axles) or the # SS33HR if your trailer has underslung leaf springs (leaf springs underneath the axles). For your trailer you will need two kits, one for each axle. I included a video review of the products mentioned for you to take a look at.

    The SumoSprings part # SS26MV will work great with your Jayco North Point 377RLBH that has the cushioned MORryde cushioned equalizers CRE3000 # MR87ZR. The two kits would not cause any problems being used at the same time and would work great together.

  • Will SumoSprings Trailer Helper Springs Add Height to 5th Wheel
    I have reached out to the manufacturer, SuperSprings, regarding a possible increase in ride height of the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 5K to 8K - Overslung # SS26MV. They were unable to give me any type of exact number in regards to an increase in ride height; they said it likely won't give any amount of actual lift to the ride height. Essentially what the SumoSprings # SS26MV do is keep your rig at the same height when they engage due...

  • Compatibility of SumoSprings Trailer Helper Springs With 4" Between Trailer Frame and U-Bolts
    You will be okay to use the SumoSprings Trailer Helper Springs # SS26MV on your trailer. SumoSprings recommends that there be between 1/4" and 1/2" of preload in the springs when installed. As the springs are 5" tall you will have 1" of preload which will put a little more preload into your springs. This may raise your suspension slightly but will not prevent your suspension from operating correctly.

  • Diameter of SS26MV SumoSprings Trailer Helper Springs
    The portion of the # SS26MV SumoSprings that contact the axle is 4 inches in diameter, with the other end with the bracket being 3-1/2 inches in diameter. The spring is 5 inches tall. How you relocate the gas line you speak of will depend on if it's a flexible or a rigid gas line. If it's flexible, you can remove the clamps that fasten the line to the trailer frame in a several foot length until you can gain enough flexibility to relocate the gas line. If it's a rigid line, you'll be...

Between the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 5K to 8K - Overslung # SS26MV you were looking at and the Roadmaster Comfort Ride Shock Absorbers I recommend the Comfort Ride hands down as it will do the best job of giving you a more comfortable ride.

  • Compatibility of SumoSprings SS26MV With 5th Wheel w/ 7K Axles
    If your 7K axles have overslung leaf springs (sits atop the axle), the SumoSprings TSS-107-47 which we sell as part # SS26MV would for well for you. The kit includes a line relocation kit in case there's a wiring harness, water or gas line in the way that would interfere with the installation. The springs are rated for 5-8K, so they'll work great with your 7K axles. The kit includes spacers to achieve the desired 1/4-1/2 inch preload, and if they're a bit too tall, the springs can be...

  • Will SumoSprings Trailer Helper Springs SS26MV Fit 4 Inch Wide Leaf Spring Plate
    I reached out to the manufacturer, SuperSprings, who said a leaf spring plate (U-bolt plate) that is 4 inches in width with 3 inches in between bolts is absolutely compatible with the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 5K to 8K - Overslung # SS26MV. So these will indeed fit your set up and give your trailer suspension a nice upgrade, absorbing road shock for an improved ride as you tow.

  • How Wide of U-Bolt Plate Will the SumoSprings SS26MV Fit Onto?
    I had the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket # SS26MV measured and the maximum spread will be 4-5/8 inches. As long as your U-Bolt plate is not wider than this, you will not need to modify it in any way. If it is wider than this, you will need to either modify the plate, or go with a different option. The Lippert Bolt-On Shock Kit w/ Heavy Duty Gas Shocks - 5,200-lb to 7,000-lb (3") Overslung Axle # LC281281 will replace your U-Bolts and plates and may be the...

  • Recommended Suspension Enhancement for an Equipment Trailer
    I do prefer the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 5K to 8K - Overslung # SS26MV over Timbren for this kind of application as the Timbren set up can be stiffer and bouncy. However, we do have another option as well. The Lippert Bolt-On Shock Kit w/ Heavy Duty Gas Shocks - 5,200-lb to 7,000-lb (3") Overslung Axle # LC281281 will absorb road shock and vibration and will end up being less bouncy than either other option.

  • Will the SumoSprings Trailer Helper Springs Work With Lippert Center Point Trailair Air-Ride

  • Will Using Leaf Springs With A Different Amount Of Leaves Be Okay On My 2018 Vanleigh 5TH Wheel?
    The number of leaves on a leaf spring is not the only determining factory in the amount of weight it can handle. The thickness of each leaf as well as what the leaf is made out of can affect the weight rating and performance of the spring. The Roadmaster Comfort Ride Leaf Spring Suspension Kit # RM-2460-2570 does use 5 leaves that are 3/8" thick. Each spring is rated for 3,500lbs which is 7,000lbs per axle. This kit upgrades your suspension by allowing the axles to act independently...

  • Which SumoSprings Trailer Helper Springs for 5080-lbs Axles
    I have a solution for you, but you won't want to use the SumoSprings # TSS-107-40 on your axle with over 5000-lbs rating on it. Instead, you'll want to use the # SS26MV which is designed for axles between 5,000-lbs and 8,000-lbs. If your axle is rated right at 5000-lbs then you could go with either set as long as you've got overslung axles.

  • Recommendations to Improve Suspension System on Keystone Outback 33RL Travel Trailer
    The basic suspension components that come on most travel trailers like your Keystone Outback 33RL and 5th wheels do not address any of the road shock and vibration like a traditional suspension system. I recommend the Dexter E-Z Flex Suspension Kit # K71-652-00 to help your suspension flex properly. You will need to confirm that your current equalizer has bolt hole center spread between 5-1/4" to 6-1/4" on the lower 2 holes. The kit includes new wet bolts that will allow you to add...

    If you're using the Andersen weight distribution hitch with the chains, it wouldn't work well with the Gen-Y # 325-GH-1024 ball mount you'd looked at as it would have more effect on the ride of the tow vehicle and minimal effect on the ride of the trailer itself. Plus, Andersen couldn't say if their weight distribution system was compatible with the Gen-Y hitch as they haven't been tested together. I'd concentrate on the suspension of the trailer itself.
