Why is one of our competitors offering Swift springs for CT4-V Blackwings?

The owner of Swift has confirmed that his company has not manufactured any springs for this competitor since 2021. And there has been no contact or discussion at all since that time. In fact, they don’t even buy directly from Swift. Their volume is low enough that they’re required to use a middle man. Regardless, it appears that maybe they used an ATS-V spring on a CT4-V Blackwing, since the physical dimensions are similar. However, the entire suspension design has been improved on the new Blackwings, and they also weigh 112 pounds more. So while using ATS-V springs may ‘work’, it’s certainly not a properly engineered solution and wouldn’t be ideal.
