I have a rough country 3.5 series II lift and I'm thinking of swapping out the coils for the Evo 4" coils. I figure with the weight of my bumpers and armor it shouldn't sit that much higher than what I'm already at. Should I be fine with just changing the coils or do I need to look into getting extra parts?

 

The ride height is very similar, shouldn't have to change anything else. I went from the series ii to EVO/Bilstein and didn't change anything else for a while and it rode great.

 

I can vouch for Ttechris. I have his old setup and it rides great. I also went from a 3.5 series 2 to the 4 inch coils. I even added a 1/2 inch spacer in the front to level it out.

 

You should be fine

 

Awesome! Ill be ordering them very soon then! Thanks for the replies.
