Hi Richard; the Replacement Spring for the 18K, 20K, or 24K Curt Helux Coil-Spring Pin Box # C58NQ is the same as the standard spring that comes with the Helux. They do not offer a heavier duty spring since it is designed to work with this spring strength.
Did the spring on your Helux wear out already? If you're within the 1-year for parts I would reach out to Curt to see if they will send you a replacement.
