Does anyone know the front spring rates of each factory suspension package?
Are the factory springs progressive rate or specific rate?

I would like to stiffen the front up on my truck with some higher rate springs.
The lower profile tires, Belltech Street performance stocks and Hellwig sway bar helped out but it still feels a little soft in the front. (body roll etc.)

I was thinking maybe if there is a stiffer factory spring then what I have I could swap those in instead of going aftermarket.

Thanks,
