Does anyone know what this number is "XJ3FCO1" I found it on the after market coils in my XJ. I am still trying to ID the name of the lift. All I know is the springs are painted machine grey and the shocks are white, there was a sticker but long since gone.
What lifts are out there?
Rancho?
Skyjacker?
Rough Country?
I think this is a two or three inch lift.

i would guess rough country but there are tons of lift brands out there
rubicon express
zone
tuff country
rusty's
pro comp
trail master
just to name a few more

The reason I am looking is because the rear is at least 2.5 inches higher and I want the front to match.

If you are satisfied with the coil performance, you can put a couple of 2" spacers in to level it out

The springs feel as though they are weak. So I think replacement may be the way to go and go 1/2 to 1 inch more so I can accommodate a winch.

Well then, springs are in order. Next you need to decide what spring rate you want. Stock is 180#/inch. There are coils out there from Clayton and Rustys with stock rates on one end to Skyjacker on the upper end

Is there a formula for figuring out what I currently by doing measurements and compression
I can remove the spring from the assembly or do a measurement with no load and count coils I'm not sure what else I can do

tinytrax78

you could just throw a spacer on top of the front coils

Jeksdad

My concern is that putting the spacers in will only work for a short time. I can barely get my ring finger between the coils as it is. The shocks have life still in them and coils will open up the travel but is that the right way to go.
I did send a note to Rancho about the numbers I found but still do not have an answer.

If you want to find out how much lift you need/want, measure from the center of the hub to the bottom of the flare and subtract 17.5" 22,5 from the crease in the fender to the hub

in my experience, machine gray is rubicon express. but who's to say they weren't painted that colour. hell, i've painted my rubicon express and skyjacker coils black. because i don't like colour under my jeep. so every thing of stand out colour gets painted black.

and if you to up 3-4 more inches, you will need new shocks anyway. i like bilstein myself. or you can go with a coil over/strut design like king or ori.
