c10 spring 6102 and cc603?

[jks67ss396]

Hi guys

Im looking at replacing my 71 c10 coils. lwb, 350/350.

i dont mind a firm, sporty ride, but dont want a harsh bone chattering ride.

Im thinking about putting in the 6102 big block springs in front, but wondered if i should use the Cargo control variable rate (CC603) out back?
I want to keep the raked look, slightly higher in the back. Would the 6102 springs stick up too high and kill the rake?

Also, Im planning on the bilstein stocks. Would those be ok with the 6102 BBC springs?

Would i be better off with the 6542 springs? (stock V8)

thanks guys
