Kings have told me that their springs are 30% stiffer than factory but the numbers on here say the spring rate for standard rate springs is 660 lb/in. Lovells have told me their springs are 30% stiffer and the rate is 800 lb/in. If the factory springs are in the order of 600 lb/in then the Lovells spring rate is about right.
What I'm geting at is are the King springs linear or progressive? If they're linear, is the spring rate 660 lb/in as quoted in the table here?
