• Recommended SumoSprings For A 2016 Forest River Wildwood 28DBUD Travel Trailer
  Hey Lance, To determine the correct SumoSprings for your 2016 Forest River Wildwood 28DBUD we'll need to first see if your leaf springs sit above or below the axle and we'll need to know the axle capacity. If your springs sit above the axle then you have overslung suspension and if they sit below the axle you have an underslung suspension. For the capacity you likely have a 3,500-4,400lb axles but you can verify by looking at the axle for the a sticker that lists the capacity. I've separated...

• How to Reduce Ford F-250 Jiggling From Grand Design Travel Trailer
  There are a few different things you can do to help with this. It would also be helpful to know what kind of jiggling you're experiencing. Does it just feel bouncy and rough? Is it side to side motion? If your travel trailer weight is more than 50% of your trucks GVWR then it would be a good idea to use a weight distribution hitch which will level you out and reduce sway. If it is more like a rough ride then you could try an upgraded equalizer, shocks, or adding something like SumoSprings...

• Replacement Suspension Components for 2024 Big Tex 16GN
  Hi Conrad! That doesn't sound good, hopefully it didn't cause you too much of a problem when those bolts failed. I would be happy to help you find some upgraded parts. However, we don't have a way of knowing what is on a particular trailer. It looks like you have 8k axles with a slipper spring suspension on there so there isn't a lot that can be swapped out/upgraded. Depending on your bolt measurements you may be able to add wet bolts like # 126B2. If you can get your leaf spring measurements...

• What AllTrek4000, Sumo Springs, and Leaf Springs do I Need for My 2016 Voltage 4150 5th Wheel?
  Hello Nathan, I reached out to MorRyde, and they informed me that the SRE4000 has been discontinued and is being replaced by the AllTrek4000. I went out to our warehouse and was able to confirm that the 35" wheelbase # MR77ZR is indeed the AllTrek4000. Unfortunately, I don’t have access to a database that shows what suspension system is installed on specific campers (though it would be pretty sweet if something like that existed), so you'll need to verify your axle spacing. Based on my...

• What Suspension Upgrades do I Need for My 2019 Powerlite Toy Hauler 29FBXL Tandem 5,100 Axles?
  Hello Jose, Looking to upgrade the suspension on your 2019 Powerlite Toy Hauler 29FBXL? That’s always a great idea. With your tandem axle setup, it’s important to match the weight rating of the leaf springs to that of your axles. Going with a spring that’s rated significantly higher than your axle capacity can result in a stiff ride and may even cause damage to your suspension over time. You’ll need to double-check your eye-to-eye measurement on the leaf springs with the trailer unloaded,...

• Best Sumo Springs For 2024 Open Range Roamer 364BSH
  Hello Camilo, thanks for reaching out. For your 2024 Open Range Roamer 364BSH I recommend the SumoSprings Trailer Helper Springs # SS33HR. These are made for axles rated between 5,000-lbs and 8,000-lbs. I am not sure exactly what axles are on your camper since that info is not listed online, but since your GVWR is 13,500 lbs your axles must be rated for something like 7,000 lbs apiece. I do suggest that you check your axle tag to verify the weight capacity but as long as it is between 5K...

• Sidewinder Pin Box for 2022 Wildwood Heritage Glen 5th Wheel
  The ST200 turret for the # 5AS16K has been discontinued. You may be able to find it still but I wasn't able to when I ran a quick search. At this time, the only Sidewinder we offer that fits the 1621 is the # RP34FR. Also, you aren't hearing from Reese because they're owned by First Brands now. Ever since this change the wait times on the phone are extremely long and many of their parts are gone or on indefinite backorder. The # RP34FR will help with clearance but it won't do anything...

• Recommended SumoSprings for a Tandem Axle Trailer
  No, you will want to go with the 5,000 lbs - 8,000 lbs SumoSprings Trailer Helper Springs w/ Line Relocation Bracket item # SS26MV assuming your axles are under your leaf springs. If they're above your leaf springs you'll need Item # SS33HR. SumoSprings use a system called progressive load control. The more weight you place on them the more they engage.

• Why Is It Not Recommended To Step Up to 8,000LB Leaf Springs Instead of 7,000LB Leaf Springs?
  We do not recommend moving from 7,000lb # e64SR to 8,000lb # DX74XR leaf springs as this creates a stiffer ride with more bounce. This causes more shock to transfer inside your RV which can cause damage to the trim and electronics. Instead I recommend adding the SumoSprings # SS26MV for overslung axles or # SS33HR for underslung axles. These help to absorb shock from transferring in your trailer as well as give you more support to reduce sag in the leaf springs. Also adding heavier leaf...

• 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.

Timbren does offer a few different options for leaf spring suspensions but you won't be able to use both the SumoSprings and Timbrens because they both mount in the same spot.

• Solution to Help Keep Tires From Rubbing on 2019 Keystone Cougar on Rough Roads
  Hey Brian, thanks for reaching out! The measurements you have are similar to the 4-Leaf Double-Eye Spring for 4,400-lb Trailer Axles # DX95CR so it sounds like your leaf springs aren't flattening out as of yet. If you drive on some pretty rough roads with the trailer close to max GVWR then that could definitely be why you're seeing tire marks. I recommend checking out the SumoSprings Jounce Springs for trailers to help soften the bounce from those roads. You'll just need to choose the...

• Solution to Prevent 2023 KZ Travel Trailer From Bottoming Out
  Hello Derek; unless the leaf springs you have now are worn out and flat you aren't going to be gaining any real height from other leaf springs. If your leaf springs run under the axle (underslung) you could move them to the top (overslung) using the Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00 (2-3/8" diameter axle) or # K71-385-00 (3" diameter axle). However, I'm guessing they're already sitting on top which is the case for most travel trailers. Another option is to use...
