Placing 600lbs fox/eibach/king spring (13 inches) in place of the 650 lb 13 icon spring?

I have icon 2.5 inch (non-resi) CO’s with 650 lb could up front on my second gen. The only problem is, these coils seem to be stiff, and do not allow the suspension to cycle through as much (so it seems) I say this because the rear of my truck is very smooth, and the front is not. Additionally, I have nothing up front other than some lights. So really, 650 is probably too much.

if I am going to get a new spring, what spring should I replace the icon 650 for?

600 lb 13 inch? Does it matter what company? Thoughts?

 

Ride quality could be a combination of standard icon valving and 650lb springs. If you have little to no weight added to the front, then a 600lb spring would be a good option. Eibach is a great brand to use

Once I compress the shocks (either due to speed or force), the shock feels much more plus, hence my thoughts to the stiffness coming from a lack of cycling. I personally am thinking it’s the 650 lb spring. Thanks for the link! As always, Accutune, you are helpful.
