Hi Brian, I'm a new customer, though I have spoken with you a few times. I just purchased Progress springs for my 06 NC and wanted to say thanks for the quick transaction. Ordered Saturday, received on Tuesday!
These will be replacing the Prokit springs that, once paired with Koni shocks, are just too low, for my likeing. I just wish I could install them before next year but, other pressing family matters take the pole. I'll post back after the install.
