• Will SumoSprings Trailer Helper Springs Help With Trailer Bottoming Out
  Instead of replacing your leaf springs, the best solution for the issue you are having bottoming out is the SumoSprings Trailer Helper Springs # TSS-106-40. The reason is these will sit on the leaf spring and take the brunt of the capacity and cushion the ride, but you do need to have 7-1/2 inches of space from the leaf spring to the trailer frame. Otherwise, if you don't have that amount of space the best option would be to mount the leaf springs on top of the axle, and for that...

• How To Fix 2019 Vanleigh Vilano 5th Wheel Trailer Leaning To One Side
  It is indeed sometimes common for a travel trailer to lean more to one side even when new as that side usually has all of the heavier appliances. This is not really any sort of warranty issue with the leaf springs but I do have an option that should help mitigate the effect of the trailer leaning to one side and that's with the SumoSprings Trailer Helper Springs part # TSS-106-40 for underslung and part # TSS-107-40 for overslung axles. This may not get you back to level but as the springs...

• Recommended Sumo Springs For Small Trailer With 3500 Lb Axle With Bouncy Suspension
  It sounds like your springs are more than likely maxed out if they have a 1750 lbs capacity and your trailer is 3400 lbs loaded. Getting in the trailer and moving around is adding extra weight to the springs as well. If the leaf springs sit below the axle then you can use SumoSprings Trailer Helper Springs w/ Line Relocation Bracket part # TSS-106-40 to support the suspension and increase the stability of the leaf springs to help them last longer. Please keep in mind these are designed...

• Determining If SumoSprings Trailer Helper Springs Fit 2021 Coachmen 192RBS with Tandem Axles
  As long as the leaf springs on your 2021 Coachmen 192RBS are underneath the axle and not on top, then the SumoSprings Trailer Helper Springs # TSS-106-40 you were looking at will fit perfectly. The springs themselves measure right at 4" so you will have a little bit of a gap but that is alright, they will still work as designed to absorb road shock while also taking some of the load off your suspension prolonging its useable life. You will install the # TSS-106-40 with the spring...

• Raising the Height of a 2019 Forest River Viking 17BH Travel Trailer for Driveway Clearance
  Without any spacers at all the SumoSprings Trailer Helper Springs # TSS-106-40 actually sit 7-1/2" tall so there will need to be a significant amount of compression for your suspension to sit properly. I do have a better solution for the problem you are running into with your 2019 Forest River Viking 17BH. I recommend using the Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00 which changes your leaf spring suspension to overslung so that your leaf springs sit on top of...

• SumoSprings Trailer Helper Springs Recommendation for OverSlung Trailer Axle
  Drop axles don't drop the distance between the trailer frame and axle as basically the drop is after the suspension and between the spindle. So the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket # TSS-106-40 would install just fine on a drop axle. But sounds like you have an overslung axle based on the distance between your leaf spring and trailer frame. So for that you'd instead want the part # TSS-107-40.

• Is There Anything to Isolate Trailer Shock for Bumps
  We do have a variety of products that are designed to help absorb shock from trailer movement like what you're talking about. For example, the SumoSprings Trailer Helper Springs # TSS-106-40 act like aftermarket bump stops for a vehicle but they help to cushion and add some control to your trailer suspension, but then the Curt Rebellion XD # C45949-22516 is a shock absorbing ball mount that helps to isolate trailer movement from transferring to the tow vehicle.

• Recommended Suspension Enhancement for Trailer with 2-1/2 Inch Wide Leaf Springs
  I have a solution for you but because of the width of your leaf springs, the SuperSprings # TSS-106-40 are not going to be a workable solution for you since they do not make a SuperSpring to work with that size leaf spring. I would instead recommend using the Timbren Trailer Suspension Enhancement System Medium-Duty Trailers # TTRA1032 which will provide you with support for up to 7000-lbs of cargo on your single axle trailer and because the bolt directly to the trailer frame and sit above...

• How to Prevent Trailer Axle from Hitting the Frame
  Installing a 4,000 lb capacity leaf spring on a trailer with a 3,500 lb capacity axle will make the suspension stiffer which could then in turn minimize the risk of the axle contacting the frame. However, this is not what I recommend to fix your problem. Instead, I recommend using the SumoSprings Trailer Helper Springs part # TSS-106-40 which will provide you with a rubber bumper between the suspension and frame as you can see in the attached photo. They will not produce a continuous rough...

  You got it! When installing the SumoSprings Trailer Helper Springs # TSS-106-40 on your trailer with tandem 3500lb axles the helper spring will get installed in the front part of the rear axle closer to the equalizer, and on the rear part of the front axle also closer to the equalizer.

I included a video review of the # TSS-106-40 for you to take a look at.

• Suspension Enhancement For Light 5th Wheel Trailer Rocking Side-to-Side When Towing
  There is going to be some rocking back and forth on uneven pavement, and while it isn't a good or bad thing for the structure as the leaf springs are designed to take on that movement, it can create a bit of an issue with handling, so the best thing to do is add some simple suspension enhancement for the trailer.

• Will SumoSprings Trailer Helper Springs Increase Space Between Frame and Axle
  The SumoSprings Trailer Helper Springs typically install compressed so they do tend to provide more space between the frame and axle in most cases but not by much and this is not really the goal of the system. If you don't have enough space between the frame and axle then this may be due to worn out leaf springs so I recommend checking this but I have attached the SumoSpring options below which are based on axle type and capacity.

• Can the Leaf Springs Be Upgraded On a Lippert 3,500 Lb Axle
  It is possible to upgrade the leaf springs on a trailer to a higher rated set but I do not recommend this as it can create a rough ride.

These will offer both additional support without decreasing the ride quality.

• What Causes Trailer Leaf Springs To Break Continuously
  Yes, leaf springs must be replaced in pairs which is why one side left go and then the other shortly after. In regards to the stent you get on a full set of leaf springs, there are really a ton of variables present here so it is hard to predict. However, if you are a full-timer then odds are your trailer is going to be subjected to harder conditions and most likely more weight than the average trailer therefore your suspension components will wear faster.

• Should I Switch To Heavier Rated Leaf Springs For My Rock Climbing Trailer?
  I recommend staying with the 4-Leaf Double-Eye Spring for 3,500-lb # SP-212275. This will ensure that you do not have to change other parts of your suspension system and the trailer has the correct ride quality. The 4-Leaf Double-Eye Spring for 4,000-lb # SP-051275 may have issues with contacting parts of the frame since the springs are 3/4-7/8" longer. To correct this your spring hangers would need to be moved. The 4-Leaf Double-Eye Spring for 6,000-lb # SP-221275 would cause you...

• How to Determine What SumoSprings Leaf Spring Enhancement Will Work
  In order to determine the correct SumoSprings Leaf Spring Enhancement System for your trailer, you need to need the weight capacity of the axles and if you have an overslung or underslung axle (which I'll explain). Based on your 2017 Montana's weight, both available kits have the right capacity, so all you need to do is find out if your Montanta has an overslung (springs sit over axle) or underslung axle (springs sit under axle). All this means is the position of the leaf springs...
