Product review (4 stars): This was a set of six, not a single spring.
This was set of six.  Not a single spring. Pisser. I needed one right away, but best to replace all six.  So I had ordered a full set of six with slower delivery. And paid to have this come next-day. Darn. I have many extra springs, or need to send back some.  But they are real nice factory OEM springs.
