Front progressive rate springs?
 

I've got 2.5" drop spindles and 1 or 2" drop springs in the front and had 4" rear springs. I replaced the rears with some 3" springs but the front us just too low. I'm not a fan on the rake.

I have Eibach lowering springs in the front now and love the way they ride and handle but they don't offer a stock height spring.

Anyone offer a progressive rate stock height spring for a 66 C10?

I've never heard of progressive rate front springs for these trucks. Rears were set-up that way for the varying loads possibly intended. The fronts are pretty set as far as 'weight' applied so no real need for them.

What is the spring rate for your current Eibach's?
