Need help choosing the right height coil

I'm trying to figure out what's the right height coils I need to to replace my vertex RC. I jack up my truck and measured 12" top of the spring to the bottom of the spring. Is this mean I have to buy 12"legnth or the 14"legnth?? I already figured out the inside diameter and the spring rate I need.

 

If the spring is still installed on the strut, it is still compressed

 

I guess I needed the 14" maybe 12 will work i just ordered it‍♂️ the good thing is my coilovers is adjustable. I think I can make it work hopefully

 

Hopefully it works

 

How did you like the set up??

 

Do you have the part number you used for your RC VERTEX COILOVERS?

 

14" actually perfect. But the eibach 700# is way too stiff. When I did my research it say 700# coil is perfect for metal bumper with a winch, but the ride was horrible.

 

So I went with 650# 14" Coil and now the ride is super smooth.

 

Have a link?? Anymore pics of your rig??

 

Been a while I forgot what brand I used for the coil. But you can buy the kings brand. Any brand you like as long as it's the right fitting. So it would be 14" length and 2.5 ID, 650lbs

 

Did you mean 3” ID for 2.5” coilovers,

 

Sorry yes you're right. 3" ID

 

Is your RC COILOVER lift a 3.5” or a 6” lift?

 

Measured the spring 9.5” as it sits on my truck, I know it’s compressed, but I feel 4.5” to compress on the coilover seems like a lot.
