Hey Dustin! I can help you find replacement leaf springs for your 2017 Momentum 350M but we are going to need more information. You already know the axle capacity is 7,000 lbs so the only other thing you need is the length of your existing leaf springs. They tend to flatten out over time so I recommend getting the flat length since it is more accurate, see the attached photo.

If you can add this information in the comments below I can see if a suitable replacement is available. For example, if you found that your flat length was 13-3/16" then the 6-Leaf Double-Eye Spring for 7,000-lb Trailer Axles - 24-7/8" Long # e64SR will work as a replacement.

Any big trips planned with your trailer before summer wraps up?
