What spring rate on KING springs for a long travel setup
 

Ordering my stuff for long travel before midnight tonight but I don't know what spring rate to get. I'm long traveling a 1992 toyota pickup with the 3.0 liter

I'll be using KING 2.5 X 8 coilovers with the total chaos gen II kit but I need to get some KING springs to go with it and I'm not sure what spring rate to go with.

They have 100, 150, 200, 250, 300, 350, 400, 425, 450, 500, 550, 600, 650, 700, 750, and 800.

I'd call the tech line for help but they are not open on sunday and i would like to take advantage of the 10% off before midnight deal.

Thanks- Blake
