Does anyone sell new super stock springs?

Cool thanks mike! I was not aware that ss springs had different numbers on each side I thought they where 6 on both. Thanks for the Info!
What would be the purpose of having 5 on one and 6 on the other?

When the car launches, the car's engine torque lifts more on the driver's side front and transfers that load more to the passenger side rear. Hence the biased spring rates.

The goal is to compensate for that torsional rotation of the car under hard launch by stiffening the passenger side rear spring.
