are you refering to the fifth and sixth coil or two springs on one shock?


look in steve smiths dirt stock car technology book for a formula to calculate things like desired spring rates and desired torque arm length to determine what you need from where your at

I run one from time to time that I got from Jeff Smith. You should have 2 400 lb springs. The short spring needs to be pre-loaded 1/2". When scaling the car make sure the tall spring is unloaded. After scaling, with the driver's weight in the seat, adjust the long spring so the adjuster nut just touches the spring. Do not pre-load it! The shock the tall spring should be on top, short on the bottom. This will place your shock up side down from normal. Start with the 5th spring at 36"-38" on the torque arm, and lean the top of the shock 2" back from the bottom of the shock at ride height.

Hope that helps!

P.S. if you need any more technical info, I'd call Jeff Smith (J&J Race Cars) 704-629-1170.
