• 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...

• 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...

• 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...

• 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...

• 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...

• 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...

• Parts Needed to Add Brakes and Suspension Enhancement to 3,500 lb Trailer Axle
  We aren't able to help with an axle replacement as we don't have the dimension axle you need. But we can help with the axle you have now. To add brakes you just need to replace the hubs with hub/drums like the # AKHD-655-35-EZ-K and brake assemblies # AKEBRK-35-SA. This has the 6 bolt pattern you are wanting. Then to move the axles in relation to the leaf springs you'd just need the part # K71-384-00 and you'd be set. Then for suspension support you'd want the part # SS33HR and you'd be set.

  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.

• 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.

• 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.

• Can Different SumoSprings Trailer Helper Springs Be Used for Better Clearance
  The SumoSprings Trailer Helper Springs # SS33HR is designed for applications where the leaf springs are under the axle - if you only have 4-1/2" of spacing between the top of the leaf spring stack and your trailer frame then that leads me to believe your suspension is either old or overloaded as your axle is going to be really close to your trailer frame. This requires 7-7/16" - 8-5/8" of clearance between the top of the spring plate to the bottom of the trailer frame. The SumoSprings...
