What is Difference between SumoSprings Trailer Helper Springs TSS-106-40 and TSS-107-40  

Updated 07/15/2022 | Published 07/14/2022



Question:

I have a 2019 Challenger Mustang 24 foot enclosed trailer with 10,000 lb gvw and tandem axles. It has under slung axles but I dont know if it needs the relocation brackets. Both these sumosprings are for 3 to 5,000 lb underslung axles what is the best choice?

Expert Reply:

The difference between the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket # TSS-106-40 and # TSS-107-40 is the orientation of the axle to the leaf springs. So since you have an underslung kit the correct part number you need is the # TSS-106-40. The main difference is the height of the spacer that fits below the jounce (blue) spring.

The relocation bracket that comes with these kits is so that you can slightly move a gas or utility line that mounts to the lower portion of the frame. There is a really strong chance your 2019 Challenger Mustang has a line like this so going with this kit would be your best option.
