Will SumoSprings Overslung Trailer Helper Springs Kit Fit with Ridges on U-Bolt Plate
Question:
Hello - I purchased and am going to install TSS-107-40/47. However, the plate that holds my springs down on one side of the trailer is not completely flat see pic I am uploading. I purchased and installed the new u-bolts and plates from e-trailer a year ago. The other passenger side of the trailer does have flat plates. Do you think i will have a problem mounting the sumo springs to these plates? Please advise. I thought I saw a picture of someones spring plate that had the same type of raised feature that my driver side plate has. Thank you!

Expert Reply:
Your U-Bolt plate design will work with the SumoSprings Overslung Trailer Helper Springs kits that you're wanting to install - I confirmed this with my contact at SuperSprings.
Now all you have to do is choose the correct weight rating for your trailer axle:
- 3K to 5K # TSS-107-40
- 5K to 8K # SS26MV
If you are unsure of your trailer axle weight rating it can be found either on an identifying sticker near the tongue of your trailer, or on a sticker in the middle of the axle itself.
