Hi Paul,

Try Kansas City Wire for your spring.l They make all kinds of spring for the auto and truck industry.
 I have them - perfect - did 20% stiff than factory. I should have  get the progressive in the front - little less dip on braking. Doing 20% is not to stiff.

By the way, this is where John Olson orders his custom springs from and they approximately they 20% stiffer.

If you have a problem with finding KCW number - I do have it at work. By the way I believe the cost was around $375 - $400 for the set of 4. I also did my compensating spring at the same time.

Hi Ron
I am interested in ordering 20% stiffer springs from Kansas city wire. Have a quote for stock but wanted to go stiffer (linear).
Before I call them, I wanted to know how you specified what you wanted.
I know I want approx. 300 lbs./inch (vs. about 250 lbs/in. for stock) my real questions is how much shorter did you specify since a stiffer spring requires a shorter free height to get the same loaded height. I have seen other comments that 3/4 of an inch is about right.
Thanks
Doug
