Can 6K Springs be Upgraded to 7K Springs on a Grand Design 320X

Updated 10/07/2024 | Published 10/04/2024

Question:

Can I put 7k springs on a 6k axle on a 320x Grand Design? Or would I be better off putting 5 leaf 6k springs. Current 4 leaf springs are fatigued so getting an accur accurate length is iffy.

Thanks for reaching out, Stan!

Normally we recommend sticking with the same weight rating, but upgrading to 7K springs for a 6K axle isn't too much of a jump so you'll be just fine doing that. If you can let me know what the center eye to center eye length is without weight on the springs (as best you can) I can make a replacement recommendation for you!

@StanK The axle tag just has info about the axle itself - anyone can install any length of spring for a given axle which is why I would need to know the length of the spring itself.
